Two identical CS amplifiers are connected is cascade. First stage is fed with a source Vsig having a resistance Rsig = 100k Ohm. A load resistance Rl = 10k Ohm is connected to the drain of the second stage. Each MOSFET is biased at Id = 0.25 mA and operates with Vov = 0.25V. Assume Va is very large. Each stage utilizes a drain resistance Rd = 10k Ohm.

(a) Sketch the equivalent circuit of the two-stage amplifier
(b) Calculate the overall voltage gain
