Discuss the below:
Q: Two identical CS amplifiers are connected in cascade. The first stage is fed with a source vsig having a resistance Rsig = 200 kΩ . A load resistance RL = 10 kΩ is connected to the drain of the second stage. Each MOSFET is biased at ID = 0.3 mA and operates with VOV = 0.2 V. Each stage utilizes a drain resistance RD = 10 kΩ.
(a) Sketch the equivalent circuit of the two-stage amplifier.
(b) Calculate the overall voltage gain Gv .
