Abstract
An integrated charge pump circuit providing a regulated output voltage controlled by a voltage regulator with reduced power requirements in which the charge pump output voltage is a substantially constant multiple of the charge pump input voltage as defined by a voltage ratio which, in turn, is defined as a selected combination of a ratio of conductances of circuit elements within a feedback loop and ratios of other voltages including selected reference voltages and the charge pump input voltage.
