The source follower amplifier in Figure P4.33 is biased at \(V^{+}=1.5 \mathrm{~V}\) and \(V^{-}=-1.5 \mathrm{~V}\). 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) The dc value of \(v_{O}\) is to be zero volts. What is the current \(I_{D Q}\) and the required value of \(V_{G S Q}\) ?

(b) Determine the small-signal voltage gain.

(c) Find the output resistance \(R_{o}\).
