ABSTRACT:
A digital PWM circuit is provided. One exemplary circuit includes a binary counter, an n-bit DAC and a comparator. The binary counter generates a plurality of binary signals in increasing and/or decreasing value. The DAC circuit generates ramp signals composed of a plurality of DC signals based on the binary signals. In another exemplary embodiment, reset circuitry is provided to control the frequency of the ramp signals.
