Claim 0:
1. A method of operating a circuit, the method comprising:
providing a switched capacitor circuit comprising first, second, third and fourth capacitors coupled to a plurality of switches;
providing a first output terminal, a second output terminal, a power input terminal and a ground coupled to the switched capacitor circuit;
repetitively cycling, by the switched capacitor circuit, between a first state and a second state;
when in the first state, coupling the first capacitor in parallel with the second capacitor, and coupling the first and second capacitors between the ground and the first output terminal;
when in the second state, coupling the first capacitor in series with the second capacitor, and coupling the first and second capacitors between the second output terminal and the ground;
when in the first and second states, connecting the first output terminal to the power input terminal via the third capacitor; and
when in the first and second states, connecting the second output terminal to ground via the fourth capacitor.
