Abstract
A method of generating pulse width modulated (PWM) signals includes receiving a coarse signal correlated to the widths of pulses to be generated in the PWM signal. Trigger signals are generated and a one-shot device is triggered in response to the trigger signals. The one-shot device generates pulses having widths correlated to the coarse signal. A control signal correlated to the widths of the pulse to be generated in the PWM signal is received and the widths of the pulses generated by the one-shot device are adjusted in response to the control signal.
