Abstract
An enhanced complementary waveform generator (ECWG) generates two complementary pulse width modulation (PWM) outputs determined by rising and falling event sources. In a simple configuration of the ECWG, the rising and falling event sources are the same signal which is a PWM signal having the desired period and duty cycle. The ECWG converts this single PWM input into dual complementary PWM outputs. The frequency and duty cycle of the dual PWM outputs substantially match those of the single input PWM signal. Blanking and deadband times may be introduced between the dual complementary PWM outputs, and the dual complementary PWM outputs may also be phase delayed.
