ABSTRACT:
A charge pump circuit having a fast rise time and reduced physical area is disclosed. The charge pump includes a plurality of stages having a non-uniform series of bootstrap capacitors. By using non-uniform capacitors at the various stages, charging rise time is enhanced while at the same time the overall physical size of the charge pump is reduced.
