Consider the simple bipolar op-amp circuit shown in Figure P13.2. The biascurrent is IQ = 0.5mA. Transistor parameters are βn = 180, βp = 120,VBE(on) = VEB(on) = 0.7 V, and VAn = VAp = ∞. (a) Design the circuit such that IC3 = 0.4mA and υ0 = 0 when υ1 = υ2 = 0. (b) Find the small signal voltage gains (i) Ad = υo1/υd and (ii) A2 = υ0/υd. (c) Determine the overall small-signal voltage gain A = υ0/υd.
