Consider the differential amplifier shown in Figure P11.13 with mismatched collector resistors. The circuit and transistor parameters are V+ = 5 V, V− = −5 V, β = 120, VBE(on) = 0.7 V, and VA = ∞. (a) For ∆R = 0, design the circuit such that ICQ1 = ICQ2 = 120 μ A and vC1 = vC2 = 3 V for v1 = v2 = 0. (b) Using the results of part (a), determine |Ad| for a two sided output, (c) For ∆R = 500 Ω, determine Ad, Acm, and CMRRdB for vo = ∆(vC1 − vC2).
