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.
