The current gain of a simple CG stage is approximate ____________(a) I

1.	The current gain of a simple CG stage is approximate ____________(a) Infinity(b) unity(c) twice(d) 0I got this question in an online interview.The query is from MOSFET Amplifier with CG Configuration topic in division FET Amplifiers of Analog Circuits
Answer» Correct option is (b) unity Easy EXPLANATION: The input to a CS stage is at the SOURCE of M1. This current simply flows into the channel and flows out of M1. Approximately, we can say that the overall current gain is unity since the gain CONTRIBUTES very low current.
