Abstract
A system and method for controlling pulse width for electronic devices in real time is disclosed. The system includes a Digital Pulse Width Modulator (DPWM), a real time calibration circuit and a delay line circuit. The real time calibration circuit is configured to ensure proper fractional delay is applied to yield correct duty cycle of the DPWM. The delay line circuit comprising a multiplexer delay line with built in decoders, modulates the pulse width for fractional clock cycle delay.
