Q2. Consider the differential amplifier where the load is a capacitor Co and the output voltage is taken differentially across Co. Let gm = 1.25 mS, RD = 1 KΩ, RSS = 1 MΩ, Co = 12π nF You are asked to: a) Draw the half circuit for the differential mode. b) Find the bandwidth of the differential mode in Hz. c) Draw the half circuit for the common mode. d) Find the bandwidth the common mode in Hz.
