Consider the circuit in Figure P11.88. The bias currents I1 and I2 are such that a zero dc output voltage is established. The transistor parameters are: Kp = 0.2 mA/V2, Kn = 0.5 mA/V2, VTP = −0.8 V, VTN = +0.8 V, and λn = λp = 0.01 V−1. Determine the small-signal voltage gain Aυ = υo/υin and the output resistance Ro.
