Abstract
A variable high voltage charge-pump system includes a plurality of unregulated switching stages and a plurality of regulated switching stages arranged in a cascaded configuration. The unregulated switching stages receive unregulated voltage input signals, and the regulated switching stages receive regulated voltage input signals. An amplifier generates the regulated voltage input signals to bring the output voltage to a desired value.
