Problem 8: The n-MOS transistor in the source follower and common gate circuits havegm = 5mA/V and large ro.(12 points) a) Find the open-circuit voltage gains (Ap) and the output

resistance (Ro) of bothcircuits separately (8 points) b) If the output of the source follower is connected to the input of the common-gateamplifier, obtain the overall voltage gain (4 points)
