Abstract
A pulse width modulation system including a pulse width modulation stage for generating a pulse width modulated signal in response to an input signal and an other pulse width modulation stage for generating an other pulse width modulated signal in response to an other input signal. Additional circuitry ensures that transitions of the pulse width modulated signal and the other pulse width modulated signal are spaced in time by a selected amount for small levels of the input signal.
