The differential amplifier in Figure P11.64 has a pair of PMOS transistors as input devices and a pair of NMOS transistors connected as an active load. The circuit is biased with IQ = 0.2 mA, and the transistor parameters are: Kn = Kp = 0.1 mA/V2, λn =0.01 V−1, λp = 0.015 V−1, VTN = 1 V, and VTP = −1 V. (a) Determine the quiescent drain-to- source voltage in each transistor, (b) Find the open-circuit differential-mode voltage gain, (c) What is the output resistance?
