Consider the circuit shown in Figure P11.39. The circuit and transistor parameters are \(V^{+}=+3 \mathrm{~V}, V^{-}=-3 \mathrm{~V}, R_{D}=360 \mathrm{k} \Omega, I_{Q}=12 \mu \mathrm{A}\), \(V_{T P}=-0.4 \mathrm{~V}, K_{p}=30 \mu \mathrm{A} / \mathrm{V}^{2}\), and \(\lambda=0\). The output resistance of the current source is \(R_{o}=4 \mathrm{M} \Omega\).

(a) Determine the \(Q\)-points of the transistors for \(v_{1}=v_{2}=0\).

(b) Determine the differential- and common-mode voltage gains for (i) \(v_{O}=v_{D 1}-v_{D 2}\) and (ii) \(v_{O}=v_{D 2}\).
