ABSTRACT:
A device for generating a high voltage includes a charge pump device that outputs a high voltage, an oscillator that supplies at least one clock signal to the charge pump device, and a regulation device. The regulation device generates a control signal to selectively stop the charge pump device based on the level of the high voltage output by the charge pump device. Additionally, the oscillator includes a shaping circuit for shaping the clock signal into a saw-tooth waveform. In a preferred embodiment, the oscillator supplies at least two clock signals to the charge pump device, and each of the clock signals has a saw-tooth waveform. A method for generating a high voltage in an integrated circuit is also provided. According to the method, at least one clock signal is generated, and the clock signal is shaped into a saw-tooth waveform. The shaped clock signal is used to generate a high voltage, and the generation of the high voltage is selectively stopped based on the level of the high voltage. In one preferred method, at least two clock signals are generated, and each of the generated clock signals is shaped in to a saw-tooth waveform.
