The bias currents in the circuit shown in Figure P11.89 are I1 = 0.25 mA and I2 = 1.0 mA. The transistor parameters are Kn = 0.5 mA/V2, Kp = 1.0 mA/V2, VTN = 0.8 V, VTP = −0.8 V, and λn= λp = 0.02 V−1. (a) Determine the resistor values R1 and R2 such that the dc value of the output voltage is zero, (b) Sketch the small-signal equivalent circuit and find the small-signal transistor parameters, (c) Determine the small-signal voltage gain Aυ = υo/υin (d) Determine the output resistance Ro.
