emitter follower is a type of negative feedback ,


Which transister is used in emitter follower circuit?

A: Any transistor of either polarity can be used as an emitter follower, The purpose of an emitter follower is to provide current to the load since it cannot provide any voltage gain


What are the differences between Emitter follower and source follower?

no difference between emiter follower and source follower


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 emitter follower?

A: When a signal is not amplified but simply taken from an emitter the reason is that the emitter will provide better current capabilities


What is Voltage gain of emitter follower?

The voltage gain of an emitter follower is theoretically 1. In practice, due to losses, it is marginally less than one.


Why emitter follower is used in circuits?

The (Class C, Common Collector) Emitter Follower is used to amplify the available current from a voltage driving circuit that might be disturbed by the load impedance. If the actual voltage value is important, the emitter follower is often teamed up with an opamp which sets the emitter voltage based on the input voltage.


Why common current is called an emitter follower?

It is not called that.


Why emitter follower is called so?

Because of the geometry of the common collector configuration, changes in base voltage appear at the emitter. Said another way, what happens at the base pretty much happens at the emitter, and the emitter can be said to "mirror" or "follow" the base. The emitter is a follower of the base, and the name emitter follower appeared and was used.


Why collector current is called an emitter follower?

It is not. You have something confused.


Emitter follower is a negative feedback amplifier using feedback as?

there is no F/B involved the emitter simply follows the changes on its base.


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.
