The transistor parameters for the circuit shown in Figure P11.29 are β = 180, VBE(on) = 0.7 VBE (except for Q4), VA = ∞ for Q1 and Q2, and VA - 100 V for Q3 and Q4. (a) Determine R1, and R2 such that I1 = 0.5 mA and IQ = 140 μA. (b) Determine the common-mode input resistance, (c) For RC = 40 kΩ, determine the common-mode voltage gain.
