Consider the diff-amp in Figure P11.46. The transistor parameters are: Kn1 = Kn2 = 50 μA/V2, λ1 = λ2 = 0.02 V−1 and VTN1 = VTN2 = 1 V. (a) Determine IS, ID1, ID2, and vO2 for v1| = v2 = 0. (b) Using the small signal equivalent circuit, determine the differential-mode voltage gain Ad = vo2/vd, the common-mode voltage gain Acm = vo2/vcm, and the CMRRdB.
