Simulation analysis of transient behavior of RF class D power amplifier due to fluctuation in load impedance

Class D amplifier is rarely reported to be broken when it is operating with a fluctuating load. This is because excessive voltage or current is imposed on the transistor of the class D amplifier. However, transient behavior of class D amplifier due to load variation was not analyzed yet. In this paper, transient behavior of a class D amplifier due to load variation is simulated with PSPICE.
