A p-channel depletion-mode MOSFET has parameters \(V_{T P}=+2 \mathrm{~V}\), \(k_{p}^{\prime}=40 \mu \mathrm{A} / \mathrm{V}^{2}\), and \(W / L=6\). Determine \(V_{S D}\) (sat) for:

(a) \(V_{S G}=-1 \mathrm{~V}\),

(b) \(V_{S G}=0\), and

(c) \(V_{S G}=+1 \mathrm{~V}\). If the transistor is biased in the saturation region, calculate the drain current for each value of \(V_{S G}\).
