Consider the circuit shown in Figure P11.39. The circuit and transistor parameters are V+ = +3 V, V− = −3 V, RD = 360 kΩ, IQ = 12 μA, VTP = −0.4 V, Kp = 30 μ.A/V2, and λ = 0. The output resistance of the current source is Ro = 4 MΩ. (a) Determine the Q-points of the transistors for v1 = v2 = 0. (b) Determine the differential- and common-mode voltage gains for (i) vO = vD1− vD2 and (ii) vO = vD2.
