Consider the differential amplifier shown in Figure PI 1.42 with mismatched transistors. The mismatched transistors result in mismatched transconductances as shown. The circuit and transistor parameters are V+ = +10 V, V− = −10 V, RD = 50kΩ, RS = 75 kΩ, VTN = 1 V, Kn = 0.15 mA/V2, and λ = 0. Determine Ad, Acm, and CMRR|dB for ∆gm/gm = 0.01 and for vO = vD1 − vD2- Assume v1 = v2 = 0 in the quiescent condition.
