In a two stage CE amplifier circuit, the ac collector resistance of the first stage depends on

Electronics and Communication Engineering (ECE) : Analog Electronics - Quiz(MCQ)

load resistance

input impedance of first stage

Both (A) and (B)

input impedance of second stage

Correct Answer : Option (D) : input impedance of second stage

Explanation : Since the first amplifier is feeding the second stage, the input impedance of second stage is the ac collector resistance of first stage.
