The parameters of the circuit in Figure 4.1 are \(V_{D D}=3.3 \mathrm{~V}\) and \(R_{D}=5 \mathrm{k} \Omega\). The transistor parameters are \(k_{n}^{\prime}=100 \mu \mathrm{A} / \mathrm{V}^{2}, W / L=40\), \(V_{T N}=0.4 \mathrm{~V}\), and \(\lambda=0.025 \mathrm{~V}^{-1}\).

(a) Find \(I_{D Q}\) and \(V_{G S Q}\) such that \(V_{D S Q}=1.5 \mathrm{~V}\).

(b) Determine the small-signal voltage gain.
