Abstract:
Charge pump circuit includes a plurality of boost capacitors. An output charge of the charge pump circuit is adjusted by selecting a number of the boost capacitors at least one of using a digital control word and programming of a wiring level. A method of boosting supply voltage uses a charge pump circuit. The method includes adjusting an output charge of the charge pump circuit by selecting a number of boost capacitors at least one of using a digital control word and by programming of a wiring level.
