Q. Write a note on feedback of emitter follower?
The emitter follower can be seen to be an example of negative feedback when the relationship
is put in the form
Which when compared to
shows that B=1. The gain with feedback is
The gain of 1 can be seen as a result of all the output being fed back to the input.
In terms of negative feedback, there exists an analogy between the operational amplifier and the power-steering mechanism of an automobile. The hydraulic pump is analogous to the p
