Abstract

A method and system for providing an output voltage greater than a voltage provided by a voltage supply in a semiconductor device are disclosed. The method and system include providing at least one oscillator and at least one voltage storage/discharge stage coupled with the at least one oscillator. The oscillator has a frequency that increases as the voltage decreases. The frequency of the oscillator determines a discharge frequency for the at least one voltage storage/discharge stage.
