Claim 7:
8. A method of operating a circuit, the method comprising:
providing an input terminal, a first output terminal and a second output terminal;
coupling first, second, third and fourth capacitors a plurality of switches;
repetitively cycling, by the plurality of switches, the first, second, third and fourth capacitors between a first state and a second state;
receiving an input voltage at the input terminal;
generating a first output voltage at the first output terminal and a second output voltage at the second output terminal, in response to receiving the input voltage at the input terminal;
in the first state, connecting in parallel the first and second capacitors with each other, and connecting the parallel connected first and second capacitors with a third capacitor such that a first fraction of the input voltage is applied at the first output terminal; and
in the second state, connecting in series the first and second capacitors with each other, and connecting the series connected first and second capacitors with a fourth capacitor such that a second fraction of the input voltage is applied at the second output terminal.
