Abstract :
Due to the nonlinearity of shunt capacitance of the class E amplifier, the output amplitude of the class E amplifier is not a linear function of the DC supply voltage of the class E amplifier. Estimating this nonlinearity is important to maintain ZVS operation in a situation of variable DC supply voltage, e.g., for a amplitude modulated (AM) power amplifier. However, there are no research results for the output amplitude of class E amplifier with nonlinear shunt capacitance. In this paper, the circuit behavior of the class E amplifier with nonlinear shunt capacitance outside designed nominal conditions is obtained using mathematical processing software MathCAD
