What else can I help you with?
What kind of feedback is used in emitter follower?
emitter follower is a type of negative feedback ,
What is the difference between a CB amplifier and CE and emitter-follower?
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
What is the applications of bootstrap amplifier?
it is a mechanism applied in an amplifier so as to raise it's input impedance.Mostly this mechanism is applied in a common collector(emitter follower) amplifier.
What is the effect of no emitter resistance on common emitter amplifier?
Limit current through emitter, Often the resistance is the load itself. So the restatnce limits current on what otherwise would act as a voltage follower.
What is the advantage of emitter follower?
The advantage of the emitter follower is that it has a positive gain of 1.
What is effect of an unbypassed resistor on the common emitter amplifier circuit?
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
Why we use emitter resistance in circuits?
The emitter resistor is connected to ground(in the case of an rc coupled amplifier).Also input signal applied at the base is grounded.Then the emitter resistor forms a feedback to the input signal (through the ground return path).So emitter resistor is also called feedback resistor.
In C-E configuration an emitter resistor is used for?
In a common-emitter (C-E) configuration, an emitter resistor is used primarily to provide temperature stability and improve linearity of the amplifier. It helps to stabilize the operating point by reducing the effects of temperature variations and transistor beta fluctuations. Additionally, the emitter resistor introduces negative feedback, which enhances linearity and bandwidth while reducing distortion. However, it also reduces the overall voltage gain of the amplifier.
Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.
Why emitter bias is more stable than fixed bias?
negative feedback
How does swamping resistor in a common emitter stabilize the voltage gain and reduce distortion?
In a common emitter amplifier, a swamping resistor is added in the emitter leg to stabilize the voltage gain by providing negative feedback. This feedback counteracts variations in transistor parameters and temperature changes, leading to a more consistent gain. Additionally, by reducing the gain sensitivity to load variations, the swamping resistor helps minimize distortion in the output signal, resulting in a cleaner amplification of the input signal. Overall, it enhances the linearity and stability of the amplifier's performance.
In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?
The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.
