Abstract
The disclosure features high-resolution pulse-width modulation (HRPWM) controllers that can include a first channel having a first coarse_on register and a first coarse_off register and a counter configured to determine a repetition rate for the first channel. When a coarse_on value of the first coarse_on register and the counter are equal, the first channel can be set 'active' and when a coarse_off value of the first coarse_off register and the counter are equal, the first channel can be set 'inactive'. The controllers can include a delay line configured to generate a set of delay locked waveforms offset by a fine resolution value and a control module configured to select a delay locked waveform from the set of delay locked waveforms and apply the selected delay locked waveform to the first channel.
