Question:
Design a class-A transformer-coupled emitter-follower amplifier to deliver \(10 \mathrm{~W}\) to an \(8 \Omega\) speaker. The ambient temperature is \(25^{\circ} \mathrm{C}\) and the maximum junction temperature is \(T_{j, \max }=150^{\circ} \mathrm{C}\). Assume the thermal resistance values are: \(\theta_{\text {dev-case }}=3.2^{\circ} \mathrm{C} / \mathrm{W}, \theta_{\text {case-snk }}=0.8^{\circ} \mathrm{C} / \mathrm{W}\), and \(\theta_{\text {snk-amb }}=4^{\circ} \mathrm{C} /\) W. Specify the power supply voltage, transformer turns ratio, bias resistor values, and transistor current, voltage, and power ratings.
