1. A method for linearizing the output of at least one power switch having switch timing error in an amplifier receiving an input signal and providing a switched output signal, said method comprising the steps of:

  • producing a compensated composite waveform by modulating said input signal with a bi-state compensating pulse waveform; and

    effecting common mode cancellation of said switch timing error by passing said compensated composite waveform through said at least one power switch having switch timing error to provide said switched output signal.
