A PMOS transistor has parameters $V_{T P}=-0.6 \mathrm{~V}, k_{p}^{\prime}=40 \mu \mathrm{A} / \mathrm{V}^{2}$, and $\lambda=0.015 \mathrm{~V}^{-1}$.

(a) (i) Determine the width-to-length ratio $(W / L)$ such that $g_{m}=1.2 \mathrm{~mA} / \mathrm{V}$ at $I_{D Q}=0.15 \mathrm{~mA}$. (ii) What is the required value of $V_{S G Q}$ ?

(b) Repeat part (a) for $I_{D Q}=0.50 \mathrm{~mA}$.
