1.	Neglecting Channel Length Modulation, what is the voltage gain from the gate to the drain of M1?(a) gm * R1(b) gm * 2R1(c) gm * R1 \|\| RO(d) 3gm * R1The question was posed to me in quiz.My doubt is from MOSFET Amplifier with CS Configuration in division FET Amplifiers of Analog Circuits
Answer» RIGHT choice is (a) gm * R1 The explanation is: We CONSTRUCT the rπ model and find that the voltage gain from the gate to the drain of the MOSFET is gm * R1. Since CHANNEL Length Modulation is neglected, the voltage gain won’t be gm * R1 \|\| RO.
