Consider the circuit in Figure P4.34. The transistor parameters are \(V_{T N}=0.6 \mathrm{~V}, k_{n}^{\prime}=100 \mu \mathrm{A} / \mathrm{V}^{2}\), and \(\lambda=0\). The circuit is to be designed such that \(V_{D S Q}=1.25 \mathrm{~V}\) and such that the small-signal voltage gain is \(A_{v}=0.85\).

(a) Find \(I_{D Q}\).

(b) Determine the width-to-length ratio of the transistor.

(c) What is the required dc value of the input voltage?
