The transistor in the common-source circuit in Figure P4.22 has the same parameters as given in Problem 4.22. The circuit parameters are \(V_{D D}=5 \mathrm{~V}\) and \(R_{D}=R_{L}=2 \mathrm{k} \Omega\).

(a) Find \(R_{S}\) for \(V_{D S Q}=2.5 \mathrm{~V}\).

(b) Determine the small-signal voltage gain.

Data From Problem 4.22:-

For the common-source amplifier in Figure P4.22, the transistor parameters are \(V_{T N}=-0.8 \mathrm{~V}, K_{n}=2 \mathrm{~mA} / \mathrm{V}^{2}\), and \(\lambda=0\). The circuit parameters are \(V_{D D}=3.3 \mathrm{~V}\) and \(R_{L}=10 \mathrm{k} \Omega\).

(a) Design the circuit such that \(I_{D Q}=0.5 \mathrm{~mA}\) and \(V_{D S Q}=2 \mathrm{~V}\).

(b) Determine the small-signal voltage gain.
