Consider the class-B output stage with complementary MOSFETs shown in Figure P8.24. The transistor parameters are \(V_{T N}=V_{T P}=0\) and \(K_{n}=K_{p}=\) \(0.4 \mathrm{~mA} / \mathrm{V}^{2}\). Let \(R_{L}=5 \mathrm{k} \Omega\).

(a) Find the maximum output voltage such that \(M_{n}\) remains biased in the saturation region. What are the corresponding values of \(i_{L}\) and \(v_{I}\) for this condition?

(b) Determine the conversion efficiency for a symmetrical sine-wave output signal with the peak value found in part (a).
