The transistor parameters for the differential amplifier shown in Figure \(\mathrm{P} 11.33\) are \(V_{T N}=0.5 \mathrm{~V}, k_{n}^{\prime}=80 \mu \mathrm{A} / \mathrm{V}^{2}, W / L=4\), and \(\lambda=0\).

(a) Find \(R_{D}\) and \(I_{Q}\) such that \(I_{D 1}=I_{D 2}=80 \mu \mathrm{A}\) and \(v_{O 2}=2 \mathrm{~V}\) when \(v_{1}=v_{2}=0\).

(b) Draw the dc load line, and plot the \(Q\)-point for \(M_{2}\).

(c) What is the maximum common-mode input voltage?
