Consider the circuit in Figure 4.14 in the text. The circuit parameters are \(V_{D D}=3.3 \mathrm{~V}, R_{D}=8 \mathrm{k} \Omega, R_{1}=240 \mathrm{k} \Omega, R_{2}=60 \mathrm{k} \Omega\), and \(R_{S i}=2 \mathrm{k} \Omega\). The transistor parameters are \(V_{T N}=0.4 \mathrm{~V}, k_{n}^{\prime}=100 \mu \mathrm{A} / \mathrm{V}^{2}, W / L=80\), and \(\lambda=0.02 \mathrm{~V}^{-1}\).

(a) Determine the quiescent values \(I_{D Q}\) and \(V_{D S Q}\).

(b) Find the small-signal parameters \(g_{m}\) and \(r_{o}\).

(c) Determine the small-signal voltage gain.
