Question

A sinusoidal signal has 1.5V at t=2S, If this signal is given to Common drain amplifier, what will be its output at t=2S?

(a) 7.5V

(b) -7.5V

(c) 0

(d) 1.5V

I have been asked this question in class test.

My question is based upon The Common Drain Amplifier topic in division Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

Correct answer is (d) 1.5V

The explanation: Input at t=2S is 1.5V, |Av|=1

 =>output=1×1.5V=1.5V.
