Consider the CMOS inverter in Figure 16.21 biased at \(V_{D D}=2.5 \mathrm{~V}\). The transistor parameters are \(V_{T N}=0.4 \mathrm{~V}, V_{T P}=-0.4 \mathrm{~V}\), and \(K_{n}=\) \(K_{p}=100 \mu \mathrm{A} / \mathrm{V}^{2}\).

(a) Find the transition points for the p-channel and \(\mathrm{n}\) channel transistors.

(b) Sketch the voltage transfer characteristics, including the appropriate voltage values at the transition points.

(c) Determine \(v_{O}\) for \(v_{I}=1.1 \mathrm{~V}\) and \(v_{I}=1.4 \mathrm{~V}\).
