A discrete/continuous time-domain analysis of a generalized class E amplifier

A simple and efficient procedure relying on a state-space description of the circuit to evaluate boundary conditions in a class-E, switching-mode, RF amplifier is described. The amplifier model used includes the on and off resistances of the active device switch. The state-space description is converted to a discrete-time representation which allows incorporating the problem into the framework of linear algebraic equations. Details on determining boundary conditions and a simple but efficient program to calculate them are provided.<
