Abstract
In an embodiment, a PWM modulation circuit includes a first circuit block configured to receive a square wave input signal and produce from the square wave input signal a triangular wave signal, a second circuit block configured to receive a modulating signal and produce a PWM signal by comparing the modulating signal with a carrier signal, a switching circuit block coupled between the first circuit block and the second circuit block and sensitive to reference signals having upper and lower reference values and selectively switchable between a carrier transfer setting in which the switching circuit block couples the first circuit block to the second circuit block to transfer the triangular wave signal as the carrier signal, and one or more carrier forcing settings for optimizing or inhibiting pulse skipping in the PWM signal, wherein the switching circuit block forces the carrier signal to the upper and lower reference values, respectively.
