Patent ID: 7688001

Claim:
A system for providing an output voltage greater than a voltage provided by a voltage supply in a semiconductor device, the system comprising: at least one oscillator having a frequency that increases as the voltage decreases, wherein the at least one oscillator includes a first phase and a second phase, the first phase including at least a first capacitor, the second phase including at least a second capacitor, the first capacitor and second capacitor charging and discharging determining the frequency, wherein the first phase also includes a first switch, a second switch, an inverter, an operational amplifier having an output and two inputs, and a transistor, wherein the first capacitor has a first side and a second side, the first side coupled with the voltage though the first switch and to the transistor through the second switch, the first side also coupled with one of the two inputs of the operational amplifier, another of the two inputs of the operational amplifier being coupled with a reference voltage, the second side of the first capacitor being coupled with ground, the output of the operational amplifier being coupled with a flip-flop; and at least one voltage storage/discharge stage coupled with the at least one oscillator, the frequency determining a discharge frequency for the at least one voltage storage/discharge stage.
