Abstract: A charge-pump device receives two complementary driving signals and a DC signal that are applied to a charge-pump stage containing a full-wave rectifier bridge configured to deliver a DC output signal. The bridge includes active switches controllable by control signals present at two control nodes. The charge-pump device further receives complementary auxiliary signals that are respectively synchronous with the complementary driving signals but have faster edges. Two resistive capacitive filters filter the complementary auxiliary signals to generate control signals at the two control nodes for controlling actuation of the active switches in the bridge.
