A simple BiCMOS amplifier is shown in Figure P13.48. The MOS transistor parameters are   and (W/L)1.2 =50, and the bipolar transistor parameters are VBE (on) = 0.7 V, β = 120, and VA = ∞. (a) Design the circuit such that ICQ = 300 µA and υ0 = 0 for υ1 = υ2 = 0. (b) Determine the small-signal differential voltage gain of the first stage A2 = υol/vd. (c) Find the small-signal voltage gain of the second stage A2 – v0/v01. (d) Determine the overall small-signal voltage gain A = v0/vd.
