Consider the circuit shown in Figure P11.11. The circuit and transistor parameters are V+ = +3 V, V− = −3 V, RC = 360 kΩ, IQ = 12 μA, β = 60, VEB(on) = 0.6 V, and VA = ∞. 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 = vC1 −vC2 and (ii) vO = vC2
