Classification: CPC H  Y | IPC H

Claim 0:
1. A circuit device comprising:
a power converter that includes:
a set of transistors each including a gate; and
an inductor coupled to the set of transistors;

a sensor configured to:
measure a voltage across the inductor; and
provide a first comparison signal based on the voltage across the inductor;

a comparator coupled to the sensor and configured to provide a second comparison signal based on the first comparison signal and a reference signal from a digital-to-analog converter (DAC), wherein the second comparison signal includes a first pulse and a second pulse;
a blanking component coupled to the comparator and configured to provide a blanking output based on a width of the second pulse of the second comparison signal being less than a threshold duration;
a timing adjustment component coupled to the blanking component and configured to provide a timing adjustment signal based on the blanking output; and
a pulse width modulator coupled to the timing adjustment component and to the gates of the set of transistors, wherein the pulse width modulator is configured to adjust a switching time of the set of transistors based on the timing adjustment signal.
