Abstract
A switched capacitor regulator in accordance with the present invention comprises a DC voltage source, a plurality of switches, a pumping capacitor, and a load capacitor. The plurality of switches may comprise semiconductor switches implemented in an integrated circuit (IC). The plurality of switches is configured to operate the switched capacitor regulator to place the regulator into a first charging stage and, alternately, a second charging stage. The switching between the first stage and the second stage results in the pumping capacitor being charged in opposing directions, while the load capacitor is always being charged in the same direction. The load capacitor is thus being charged in both the first charging stage and the second charging stage.
