DC bias
When describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean value of the waveform. If the mean amplitude is zero, there is no DC offset. In contrast, various other frequencies are analogous to superimposed AC voltages or currents, hence called AC components or AC coefficients.
The term originated in electronics, where it refers to a direct current voltage, but the concept has been extended to any representation of a waveform. The term's use is extended to two-dimensional transformations like the discrete cosine transform used in JPEG.
A waveform without a DC component is known as a DC-balanced or DC-free waveform. DC-balanced waveforms are useful in communications systems to avoid voltage imbalance problems between connected systems or components.
DC offset is usually undesirable when it causes saturation or change in the operating point of an amplifier. An electrical DC bias will not pass through a transformer; thus a simple isolation transformer can be used to block or remove it, leaving only the AC component on the other side. In signal processing terms, DC offset can be reduced in real-time by a high-pass filter. When one already has the entire waveform, subtracting the mean amplitude from each sample will remove the offset. Often, very low frequencies are called "slowly changing DC" or "baseline wander".

Bias
Bias is an inclination or outlook to present or hold a partial perspective, often accompanied by a refusal to consider the possible merits of alternative points of view. Biases are learned implicitly within cultural contexts. People may develop biases toward or against an individual, an ethnic group, a nation, a religion, a social class, a political party, theoretical paradigms and ideologies within academic domains, or a species. Biased means one-sided, lacking a neutral viewpoint, or not having an open mind. Bias can come in many forms and is related to prejudice and intuition.
In science and engineering, a bias is a systematic error.
Cognitive biases
A cognitive bias is a repeating or basic misstep in thinking, assessing, recollecting, or other cognitive processes. That is, a pattern of deviation from standards in judgment, whereby inferences may be created unreasonably. People create their own "subjective social reality" from their own perceptions, their view of the world may dictate their behaviour. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality. However some cognitive biases are taken to be adaptive, and thus may lead to success in the appropriate situation. Furthermore, cognitive biases may allow speedier choices when speed is more valuable than precision. Other cognitive biases are a "by-product" of human processing limitations, coming about because of an absence of appropriate mental mechanisms, or just from human limitations in information processing.

Biasing
Biasing in electronics is the method of establishing predetermined voltages or currents at various points of an electronic circuit for the purpose of establishing proper operating conditions in electronic components. Many electronic devices such as transistors and vacuum tubes, whose function is processing time-varying (AC) signals also require a steady (DC) current or voltage to operate correctly — a bias. The AC signal applied to them is superposed on this DC bias current or voltage. The operating point of a device, also known as bias point, quiescent point, or Q-point, is the steady-state voltage or current at a specified terminal of an active device (a transistor or vacuum tube) with no input signal applied.
The term is also used for an alternating current (AC) signal applied to some electronic devices which is similarly required for correct operation, such as the tape bias signal applied to magnetic recording heads used in magnetic tape recorders.
Overview
In electronic engineering, the term bias has the following meanings:

Bias (mythology)
In Greek mythology, Bias (/ˈbaɪ.əs/; Ancient Greek: Βίας) was a brother of Melampus who received one third of the Kingdom of Argos (see Melampus for more information).
Marriages
Bias married his cousin Pero who was the daughter of Neleus. It was said that Neleus would not allow his daughter to marry anyone unless the suitor brought him the oxen of Iphiclus. This Melampus achieved with courage and using his supernatural abilities of speaking with animals, upon winning the challenge he arranged the marriage of Pero and Bias, they had one child together, Talaus.
When Pero died Bias remarried Iphianassa, daughter of Proetus, after Melampus had cured her, her sisters and the women of Argive from madness. He received one third of Proetus's kingdom all of which he gave to Bias. Bias and Iphianassa had a daughter Anaxibia who married Pelias, to whom she bore Acastus and several daughters. According to Pausanias, Amythaon is the father of Bias and Melampus. Their mother was Idomene, daughter of Pheres or Abas of Argos.

Can you figure out the rule?
Did you see the exponents pattern? http://youtu.be/AVB8vRC6HIY
Why do you make people look stupid? http://bit.ly/12Fmlpl
How do you investigate hypotheses? Do you seek to confirm your theory - looking for white swans? Or do you try to find black swans? I was startled at how hard it was for people to investigate number sets that didn't follow their hypotheses, even when their method wasn't getting them anywhere.
In the video I say "when people came to Australia..." by which I meant, "when Europeans who believed all swans were white came to Australia..." I did not mean any offence to Indigenous Australians who were already in Australia at that time. Please accept my apologies for the poor phrasing if you were offended by it.
This video was inspired by The Black Swan by Nassim Taleb and filmed by my mum. Thanks mum!
Partly my motivation came from responses to my Facebook videos - social media marketers saying 'Facebook ads have worked for me so there can't be fake likes.' Just because you have only seen white swans, doesn't mean there are no black ones. And in fact marketers are only looking for white swans. They think it was invalid of me to make the fake Virtual Cat page: 'well of course if it's a low quality page you're going to get low quality likes.' But my point is this is black swan bait, something they would never make because their theory is confident in the exclusive existence of white swans.

David Eagleman, a neuroscientist at Stanford and host of the Inner Cosmos podcast, explores how our brains shape the reality we experience and why we often accept our perceptions as the only truth. From a young age, we develop our understanding of the world based on limited experiences and biases, which can lead us to form narrow views about what's true.
Eagleman explains that our genetics and life experiences wire our brains in unique ways, meaning that each of us sees the world a little differently. He introduces the idea of "perceptual genomics," which looks at how slight genetic differences influence our perception of reality. He also discusses how our brains naturally create in-groups and out-groups, a tendency rooted in evolution that affects how much empathy we feel for others.
To overcome these biases, Eagleman suggests that we start by recognizing our own prejudices, understanding the tactics of dehumanization, and connecting with others through shared interests. This approach helps us appreciate the diverse realities others experience, ultimately contributing to a more empathetic and understanding society.

David Eagleman, a neuroscientist at Stanford and host of the Inner Cosmos podcast, explores how our brains shape the reality we experience and why we often accept our perceptions as the only truth. From a young age, we develop our understanding of the world based on limited experiences and biases, which can lead us to form narrow views about what's true.
Eagleman explains that our genetics and life experiences wire our brains in unique ways, meaning that each of us sees the world a little differently. He introduces the idea of "perceptual genomics," which looks at how slight genetic differences influence our perception of reality. He also discusses how our brains naturally create in-groups and out-groups, a tendency rooted in evolution that affects how much empathy we feel for others.
To overcome these biases, Eagleman suggests that we start by recognizing our own prejudices, understanding the tactics of dehumanization, and connecting with others through shared interests. This approach helps us appreciate the diverse realities others experience, ultimately contributing to a more empathetic and understanding society.

Billboard Recording Music Artist Lovari and Josie a transgender counselor and Independent voter join Carmella Cann as they discuss the decline in public confidence around bias and reliability of major media sources today.
Lovari speaks out and shares his deep personal experience of being bullied by the media and Jimmy Kimmel for supporting President-elect Donald Trump. Would Taylor Swift have been treated the same way for supporting Harris or is there a double standard? There has been much public criticism that many media sources are biased, and both Josie and Lovari talk about the media polarization and how right and left-leaning media insisting they are neutral, but are they?

Transistor Biasing Transistor Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor The steady state operation of a transistor depends a great deal on its base current, collector voltage, and collector current values and therefore, if the transistor is to operate correctly as a linear amplifier, it must be properly biased around its operating point. Establishing the correct operating point requires the selection of bias resistors and load resistors to provide the appropriate input current and collector voltage conditions.

CV Measurements Tutorial || Experimentally Determine the Doping Concentrations in a Diode 🔬📊 🧪💡
Determining the doping concentrations in GaN (Gallium Nitride) high-power PIN diodes is crucial for optimizing their performance in power electronics and other applications. 📏🔬 The Capacitance-Voltage (CV) measurement technique using instruments like the Keithley 590 CV Analyzer is particularly valuable in this context. In a GaN PIN diode, the intrinsic (i-) layer's doping concentration significantly affects its electrical characteristics, such as breakdown voltage and leakage current. 🌟 The CV measurement process involves applying a voltage across the diode and measuring the resulting capacitance as a function of voltage. This capacitance is directly related to the depletion width of the diode, which in turn depends on the doping concentration in the i-layer. Specifically, the Keithley ...

Transistor Biasing
Transistor Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor
The steady state operation of a transistor depends a great deal on its base current, collector voltage, and collector current values and therefore, if the transistor is to operate correctly as a linear amplifier, it must be properly biased around its operating point.
Establishing the correct operating point requires the selection of bias resistors and load resistors to provide the appropriate input current and collector voltage conditions. The correct biasing point for a bipolar transistor, either NPN or PNP, generally lies somewhere between the two extremes of operation with respect to it being either “fully-ON” or “fully-OFF” along its DC load line. This central operating point is called the “Quiescent Operating Point”, or Q-point for short.
When a bipolar transistor is biased so that the Q-point is near the middle of its operating range, that is approximately halfway between cut-off and saturation, it is said to be operating as a Class-A amplifier. This mode of operation allows the output voltage to increase and decrease around the amplifiers Q-point without distortion as the input signal swings through one complete cycle.

Transistor Biasing
Transistor Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor
The steady state operation of a transistor depends a great deal on its base current, collector voltage, and collector current values and therefore, if the transistor is to operate correctly as a linear amplifier, it must be properly biased around its operating point.
Establishing the correct operating point requires the selection of bias resistors and load resistors to provide the appropriate input current and collector voltage conditions. The correct biasing point for a bipolar transistor, either NPN or PNP, generally lies somewhere between the two extremes of operation with respect to it being either “fully-ON” or “fully-OFF” along its DC load line. This central operating point is called the “Quiescent Operating Point”, or Q-point for short.
When a bipolar transistor is biased so that the Q-point is near the middle of its operating range, that is approximately halfway between cut-off and saturation, it is said to be operating as a Class-A amplifier. This mode of operation allows the output voltage to increase and decrease around the amplifiers Q-point without distortion as the input signal swings through one complete cycle. In other words, the output is available for the full 360o of the input cycle.

Determining the doping concentrations in GaN (Gallium Nitride) high-power PIN diodes is crucial for optimizing their performance in power electronics and other applications. 📏🔬 The Capacitance-Voltage (CV) measurement technique using instruments like the Keithley 590 CV Analyzer is particularly valuable in this context.
In a GaN PIN diode, the intrinsic (i-) layer's doping concentration significantly affects its electrical characteristics, such as breakdown voltage and leakage current. 🌟 The CV measurement process involves applying a voltage across the diode and measuring the resulting capacitance as a function of voltage. This capacitance is directly related to the depletion width of the diode, which in turn depends on the doping concentration in the i-layer.
Specifically, the Keithley 590 CV Analyzer applies a small AC voltage signal to the diode and detects the resulting AC current and phase shift. 📊 By analyzing these signals, researchers can extract the capacitance at different bias voltages. From the capacitance-voltage characteristics, they can infer the doping concentration profile within the GaN PIN diode's i-layer.
Accurate measurement of the i-layer doping concentration is crucial for optimizing the diode's performance parameters such as forward and reverse bias characteristics, switching speed, and overall efficiency in high-power applications. ⚡️ This experimental approach not only ensures precise characterization of GaN PIN diodes but also supports advancements in semiconductor device design and fabrication, ultimately driving innovation in power electronics and related industries. 🌐

Can you figure out the rule?
Did you see the exponents pattern? http://youtu.be/AVB8vRC6HIY
Why do you make people look stupid? http://bit.ly/12Fmlpl
How do you investigate hypotheses? Do you seek to confirm your theory - looking for white swans? Or do you try to find black swans? I was startled at how hard it was for people to investigate number sets that didn't follow their hypotheses, even when their method wasn't getting them anywhere.
In the video I say "when people came to Australia..." by which I meant, "when Europeans who believed all swans were white came to Australia..." I did not mean any offence to Indigenous Australians who were already in Australia at that time. Please accept my apologies for the poor phrasing if you were offended by it.
This video was inspired by The Black Swan by Nassim Taleb and filmed by my mum. Thanks mum!
Partly my motivation came from responses to my Facebook videos - social media marketers saying 'Facebook ads have worked for me so there can't be fake likes.' Just because you have only seen white swans, doesn't mean there are no black ones. And in fact marketers are only looking for white swans. They think it was invalid of me to make the fake Virtual Cat page: 'well of course if it's a low quality page you're going to get low quality likes.' But my point is this is black swan bait, something they would never make because their theory is confident in the exclusive existence of white swans.

David Eagleman, a neuroscientist at Stanford and host of the Inner Cosmos podcast, explores how our brains shape the reality we experience and why we often accept our perceptions as the only truth. From a young age, we develop our understanding of the world based on limited experiences and biases, which can lead us to form narrow views about what's true.
Eagleman explains that our genetics and life experiences wire our brains in unique ways, meaning that each of us sees the world a little differently. He introduces the idea of "perceptual genomics," which looks at how slight genetic differences influence our perception of reality. He also discusses how our brains naturally create in-groups and out-groups, a tendency rooted in evolution that affects how much empathy we feel for others.
To overcome these biases, Eagleman suggests that we start by recognizing our own prejudices, understanding the tactics of dehumanization, and connecting with others through shared interests. This approach helps us appreciate the diverse realities others experience, ultimately contributing to a more empathetic and understanding society.

Lovari speaks out and shares his deep personal experience of being bullied by the media and Jimmy Kimmel for supporting President-elect Donald Trump. Would Taylor Swift have been treated the same way for supporting Harris or is there a double standard? There has been much public criticism that many media sources are biased, and both Josie and Lovari talk about the media polarization and how right and left-leaning media insisting they are neutral, but are they?

DC bias
When describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean value of the waveform. If the mean amplitude is zero, there is no DC offset. In contrast, various other frequencies are analogous to superimposed AC voltages or currents, hence called AC components or AC coefficients.
The term originated in electronics, where it refers to a direct current voltage, but the concept has been extended to any representation of a waveform. The term's use is extended to two-dimensional transformations like the discrete cosine transform used in JPEG.
A waveform without a DC component is known as a DC-balanced or DC-free waveform. DC-balanced waveforms are useful in communications systems to avoid voltage imbalance problems between connected systems or components.
DC offset is usually undesirable when it causes saturation or change in the operating point of an amplifier. An electrical DC bias will not pass through a transformer; thus a simple isolation transformer can be used to block or remove it, leaving only the AC component on the other side. In signal processing terms, DC offset can be reduced in real-time by a high-pass filter. When one already has the entire waveform, subtracting the mean amplitude from each sample will remove the offset. Often, very low frequencies are called "slowly changing DC" or "baseline wander".

We've gone over the PN junction of a diode in a previous video and now we're talking about when it's forward biased! This is when things get serious - understanding a forwarded biased PN junction not only helps in understanding how a diode works but practically any semiconductor devices - transistors, thyristor, TRIAC, photocouplers, etc. We're laying the foundation for conceptually understanding how *any* current electronic device works with this. Once we go over the reverse biased junction, it should all come together! Subscribe to CircuitBread for more videos on intermediate electronics!

Transistor Biasing
Transistor Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor
The steady state operation of a transistor depends a great deal on its base current, collector voltage, and collector current values and therefore, if the transistor is to operate correctly as a linear amplifier, it must be properly biased around its operating point.
Establishing the correct operating point requires the selection of bias resistors and load resistors to provide the appropriate input current and collector voltage conditions. The correct biasing point for a bipolar transistor, either NPN or PNP, generally lies somewhere between the two extremes of operation with respect to it being either “fully-ON” or “fully-OFF” along its DC load line. This central operating point is called the “Quiescent Operating Point”, or Q-point for short.
When a bipolar transistor is biased so that the Q-point is near the middle of its operating range, that is approximately halfway between cut-off and saturation, it is said to be operating as a Class-A amplifier. This mode of operation allows the output voltage to increase and decrease around the amplifiers Q-point without distortion as the input signal swings through one complete cycle. In other words, the output is available for the full 360o of the input cycle.

Determining the doping concentrations in GaN (Gallium Nitride) high-power PIN diodes is crucial for optimizing their performance in power electronics and other applications. 📏🔬 The Capacitance-Voltage (CV) measurement technique using instruments like the Keithley 590 CV Analyzer is particularly valuable in this context.
In a GaN PIN diode, the intrinsic (i-) layer's doping concentration significantly affects its electrical characteristics, such as breakdown voltage and leakage current. 🌟 The CV measurement process involves applying a voltage across the diode and measuring the resulting capacitance as a function of voltage. This capacitance is directly related to the depletion width of the diode, which in turn depends on the doping concentration in the i-layer.
Specifically, the Keithley 590 CV Analyzer applies a small AC voltage signal to the diode and detects the resulting AC current and phase shift. 📊 By analyzing these signals, researchers can extract the capacitance at different bias voltages. From the capacitance-voltage characteristics, they can infer the doping concentration profile within the GaN PIN diode's i-layer.
Accurate measurement of the i-layer doping concentration is crucial for optimizing the diode's performance parameters such as forward and reverse bias characteristics, switching speed, and overall efficiency in high-power applications. ⚡️ This experimental approach not only ensures precise characterization of GaN PIN diodes but also supports advancements in semiconductor device design and fabrication, ultimately driving innovation in power electronics and related industries. 🌐
