Figure Q1(a) shows a Class A power amplifier circuit. Given the output signal is as shown in the figure, where Vm is the peak voltage and T is the period. For all transistors, you may neglect VBE and VCE(sat) in your calculations. (i) Derive an equation for power conversion efficiency, in terms of Vm, VCC, I and RL. Hence, deduce the maximum power conversion efficiency that is achievable. (ii) Determine the worst-case average power dissipation in each transistor under normal condition (i.e. RL is not open or short)
