Why emitter is always forward biased with respect to base?
It is because the emitter is the source of charge carriers and we require to move these charge carriers into base which is obtained only by forward baising the base emitter junction.
Explian the working of a common-source amplifier and a common drain amplifier?
Configuration Voltage Gain Current Gain Input Resistance Output Resistance Common- Source AV >1 - ∞ Moderate to high Source-Follower AV ≈ 1 - ∞ Low Common- Gate AV > 1 Ai ≈ 1 Low Moderate to high Both the common-gate and common source has voltage gain of greater that 1 compared with the voltage gain of source- follower which is less than or approximately equal to 1 . The input resistance of both common-source and source follower is high typically ranges from kilo ohms and above while common-gate has a low input impedance ranges from hundred ohms or below. The output resistance of both common-gate and common-source are dominated by RD while source follower has low output impedance and is not dominated by RD
What is the difference between upstream and downstream in electrical network?
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
Why CMOS connected to VDD and NMOS to Vcc?
Error on schematic. All MOS is powered by Vdd and/or Vss (drain/source). Only bipolar is powered by Vcc and/or Vee (collector/emitter).
What are the three element of a transistor?
For a BJT transistor the three basic elements are collector, base and emitter. For a FET transistor are drain, gate and source which are analogous for the BJT parts mentioned before.
What are the practical applications of the emitter follower?
See an analog design textbook for some specific examples but the gist of emitter follower's purpose in life is to transform a high output resistance signal source to achieve a signal with lower output resistance.
What are three configurations that can be used with FET devices?
configurations of Common-source (CS), Common-drain (CD) or Source-follower (SF) and the Common-gate (CG) available for most FET devices. These three JFET amplifier configurations correspond to the common-emitter, emitter-follower and the common-base configurations using bipolar transistors.
What is the difference between light and reflected light?
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
Why you use negative source in emitter biasing?
to get the base- emitter junction forward bias we should connect the negative of the diode with the negative of the battery and the positive of the diode with the positive of the diode so we should connect negative source in the emitter
What is meant by dependent source?
A dependent source is a source that is dependent on, i.e. a function of, some other thing in the circuit. Often, a transistor is represented as a dependent current source, with collector-emitter current being dependent on base-emitter current times hFe, or beta-gain, limited by the collector-emitter resistor network.
What is the differences between money and education?
Mony is power money is source of survivel source of fame
Why emitter is always forward biased with respect to base?
It is because the emitter is the source of charge carriers and we require to move these charge carriers into base which is obtained only by forward baising the base emitter junction.
Applications of source follower with bootstrapped gate resistance?
reduce distortion,
What was technetium used for?
Technetium-99m is used as tracer in medicine and as beta-emitter standard source.
What is the original source for wind?
Wind blows from high pressure zones to low pressure zones. It does not have a source, it is produced by differences in pressure between different areas.
How does curium work?
Curium is a strong alpha particle emitter and can be used as alpha particle source or in isotopic heat generators.
How do you wire a 120v A base emter for 120v?
To wire a 120V A base emitter for 120V, you would typically connect the emitter to the ground, the base to the input voltage source (120V), and the collector to the load. Ensure you follow proper safety precautions and consult the specific datasheet for the A base emitter you are using for correct wiring instructions.
