Abstract
A charge pump circuit is disclosed. The charge pump circuit includes a first circuit powered by a first supply voltage and configured to adjust a voltage of an output in response to first and second sets of control signals. The first circuit includes a set of transistors having respective switching voltages. A control circuit powered by a second voltage, less than the first supply voltage, is configured to generate the first and second sets of control signals. A voltage shifting circuit is configured to bias voltages of the first and second sets of control signals relative to the switching voltages.
