Consider the circuit in Figure P3.47.

(a) The nominal transistor parameters are \(V_{T N}=0.6 \mathrm{~V}\) and \(k_{n}^{\prime}=120 \mu \mathrm{A} / \mathrm{V}^{2}\). Design the width-to-length ratio required in each transistor such that \(I_{D Q}=0.8 \mathrm{~mA}, V_{1}=2.5 \mathrm{~V}\), and \(V_{2}=6 \mathrm{~V}\).

(b) Determine the change in the values of \(V_{1}\) and \(V_{2}\) if the \(k_{n}^{\prime}\) parameter in each transistor changes by (i) +5 percent and (ii) -5 percent.

(c) Determine the values of \(V_{1}\) and \(V_{2}\) if the \(k_{n}^{\prime}\) parameter of \(M_{1}\) decreases by 5 percent and the \(k_{n}^{\prime}\) parameter of \(M_{2}\) and \(M_{3}\) increases by 5 percent.
