Abstract: An embodiment circuit includes a first voltage divider coupled between a first voltage level and a ground potential. The circuit further includes an error amplifier having a first input terminal coupled to a node between a first resistive element and a second resistive element of the first voltage divider. The circuit further includes a second voltage divider coupled between a second voltage level and a reference voltage, wherein a second input terminal of the error amplifier is coupled to a node between a third resistive element and a fourth resistive element of the second voltage divider, and wherein an output voltage of the error amplifier is configured to control a potential difference between the first voltage level and the second voltage level.

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.

Abstract: A circuit including: a plurality of first switches connected in parallel between a first terminal and a second terminal; and a control circuit capable of implementing the following steps at each period of a clock signal: comparing the voltage between the first and second terminals with a reference voltage; if the voltage between the first and second terminals is greater than the reference voltage, turning on one of the first switches without modifying the state of the other switches; and if the voltage between the first and second terminals is smaller than the reference voltage, turning off one of the first switches without modifying the state of the other switches.
