The differential amplifier with the configuration shown in Figure 11.36 is to be designed to achieve a differential-mode voltage gain of \(A_{d}=400\). The circuit parameters are to be \(V^{+}=+5 \mathrm{~V}, V^{-}=-5 \mathrm{~V}\), and \(I_{Q}=200 \mu \mathrm{A}\). The available transistors have parameters for the PMOS of \(V_{T P}=-0.5 \mathrm{~V}, k_{p}^{\prime}=40 \mu \mathrm{A} / \mathrm{V}^{2}\), and \(\lambda_{p}=0.02 \mathrm{~V}^{-1}\), and for the NMOS of \(V_{T N}=+0.5 \mathrm{~V}, k_{n}^{\prime}=80 \mu \mathrm{A} / \mathrm{V}^{2}\), and \(\lambda_{n}=0.015 \mathrm{~V}^{-1}\).
