ABSTRACT:
A first charge pump includes a collection of voltage adder stages. The first voltage adder stage receives an input voltage VCC and in response to a clock signal provides a first voltage signal alternating between 2*VCC and VCC. The Nth voltage adder stage receives an input voltage VCC and a first voltage signal from the preceding stage, and provides a second voltage signal alternating between N*VCC and VCC. The capacitors included within each adder stage are required to sustain a maximum voltage of VCC. In an alternate embodiment the first charge pump may be combined with one or more voltage doubler stages to produce even higher output voltages.
