Patent ID: 7135910

Claim:
A method of generating voltages, comprising in order: (a) charging a first plurality of capacitors, (b) serially coupling a first plurality of charged capacitors such that, within the first plurality of charged capacitors, a positive terminal of a charged first capacitor couples to a negative tenninal of a charged second capacitor and so on, (c) charging a second plurality of capacitors from voltages produced by the first plurality of serially-coupled charged capacitors, (d) serially coupling the second plurality of charged capacitors such that, within the second plurality of capacitors, a positive terminal of a charged first capacitor couples to a negative terminal of a charged second capacitor and so on, (e) charging the first plurality of capacitors from voltages produced by the second plurality of serially-coupled charged capacitors, and (f) repeating (b)–(e) in order a multiple number of times.
