The transistor parameters in the CMOS inverter are \(V_{T N}=0.35 \mathrm{~V}\), \(V_{T P}=-0.35 \mathrm{~V}, k_{n}^{\prime}=80 \mu \mathrm{A} / \mathrm{V}^{2}\), and \(k_{p}^{\prime}=40 \mu \mathrm{A} / \mathrm{V}^{2}\). Let \(V_{D D}=1.8 \mathrm{~V}\).

(a) Determine the peak current in the inverter during a switching cycle for \((W / L)_{n}=2\) and \((W / L)_{p}=4\).

(b) Repeat part (a) for \((W / L)_{n}=2\) and \((W / L)_{p}=6\).

(c) Repeat part (a) for \((W / L)_{n}=(W / L)_{p}=4\).
