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 \(I_{Q}=0.2 \mathrm{~mA}\), and the transistor parameters are: \(K_{n}=K_{p}=0.1 \mathrm{~mA} / \mathrm{V}^{2}, \quad \lambda_{n}=0.01 \mathrm{~V}^{-1}, \quad \lambda_{p}=0.015 \mathrm{~V}^{-1}\), \(V_{T N}=1 \mathrm{~V}\), and \(V_{T P}=-1 \mathrm{~V}\).

(a) Determine the quiescent drain-tosource voltage in each transistor.

(b) Find the open-circuit differentialmode voltage gain.

(c) What is the output resistance?
