A Self bias configuration contains RD=3.3,Rs=1 KΩ,RG=1MΩ and gm=1.

1.	A Self bias configuration contains RD=3.3,Rs=1 KΩ,RG=1MΩ and gm=1.5mS. Determine Av?(a) -2(b) 3(c) -4(d) 5This question was posed to me by my school principal while I was bunking the class.My question is taken from The Common Source Amplifier topic in section Field-Effect Transistors of Electronic Devices & Circuits
Answer» CORRECT choice is (a) -2 The EXPLANATION: Av=-gm RD/ (1+gm RS) because RS is GIVEN and it is not bypassed. Av=-1.5×3.3KΩ/ (1+1.5×1) Av=-2.
