ABSTRACT:
An improved charge pump circuit efficiently utilizes multiple charge pump stages to produce output voltages much larger than the power supply voltage by incorporating, in some embodiments, two parallel strings of series-coupled charge pump stages. Each corresponding charge pump stage in one string is controlled at least by a node in the corresponding charge pump stage of the other string.
