Consider a Class-D amplifier using two transistors in a complementary push-pull configuration. Vdc Vdc Drive 0 0000 RL Figure: Class-D series resonant amplifier. a) The output node voltage of a single transistor when conducting is shown in the figure as squared pulse. Find its average value, i.e. find the average supply voltage of each transistor supplied to series RLC circuit. b) Let the load voltage be, VL = V pksin(wt). Assuming the top transistor is conducting during positive load cycle, find the average of this load current during the positive half cycle in terms of V pk and RL.
