Consider the transformer-coupled emitter follower in Figure P8.36. Assume an ideal transformer. The transistor parameters are \(\beta=100\) and \(V_{B E}=\) \(0.7 \mathrm{~V}\).

(a) Design the circuit to provide a current gain at \(A_{i}=i_{o} / i_{i}=80\).

(b) If the magnitude of the signal emitter current is limited to \(0.9 I_{C Q}\) to prevent distortion, determine the power delivered to the load, and the conversion efficiency.
