ABSTRACT:
A charge pump circuit includes MOS capacitors configured to operate in the accumulation region, resulting in a substantially constant capacitance over the operational range. In a particularly preferred embodiment, a char ge pump uses multiple stages of p-channel MOS capacitors. In accordance with a further aspect of the present invention, oxide thicknesses of the p-channel MOS capacitors are optimized in accordance with the requirements of each stage.
