The bias voltages for the diff-amp shown in Figure P11.10 are V+ = 3 V and V− = −3 V. The transistor current gains are β = 80, the nominal value of VBE(on) is 0.6 V, and VA = ∞. (a) Design the circuit such that the quiescent collector currents are 50 μA and vC1 = vC2 = −1.5 V for v1 = v2 = 0. (b) Determine vC1 and vC2 when (i) v1, = v2 = 1 V and (ii)v1 = 0.994 V, v2 = 1.006 V.
