ABSTRACT:
A switched-capacitor regulator is provided for regulating the output voltage of a voltage supply. The switched-capacitor regulator includes a supply input terminal capable of receiving a supply voltage, two or more flying capacitors, a regulation switch located between each flying capacitor and the supply input terminal, and a voltage control circuit. The activity of the regulation switches is controlled by the voltage control circuit. In one embodiment of the invention, the voltage control circuit includes a feedback resistance area having one or more feedback resistors located between the output of the flying capacitors and a ground terminal, a first gain stage connected to the feedback resistance area, and two or more second switchable gain stages, which are each connected to a regulation switch and the first gain stage. The switched-capacitor regulator operates in pseudo-continuous regulator mode using three-stage switchable operational amplifiers with time-multiplexed pole-splitting compensation.
