Abstract
A pulse width modulator includes at least one input for receiving an input signal and pulse width modulation circuitry for generating a pulse width modulated stream and another pulse width modulated stream. The pulse width modulated stream and the another pulse width modulated stream are nominally out of phase and together represent the received input signal. A summer sums the pulse width modulated stream and the another pulse width modulated stream to generate an analog output signal.
