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.

Claim (Index 7):
A device, comprising:\n a first circuit block configured to receive a square wave input signal having rising and falling edges 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 pulse width modulated 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, wherein the switching circuit block comprises reference inputs configured to receive reference signals having upper and lower reference values, wherein the switching circuit block is selectively switchable between:\n 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 \n a carrier forcing setting in which the switching circuit block applies to the second circuit block the reference signals by forcing the carrier signal to respective upper and lower reference values; \n an input circuit block configured to receive an input signal and provide to the second circuit block the modulating signal as a function of the input signal; a switching power stage driven by the pulse width modulated signal; and a low-pass filter circuit configured to receive a switching power signal from the switching power stage and produce an amplified replica of the input signal.
