ABSTRACT:
A negative charge pump circuit for low voltage and wide voltage range applications. The charge pump includes two single-stage p-type pumps. One of the pumps is used to charge a circuit node down to a threshold voltage .vertline.Vt.sub.p .vertline. less than a desired voltage. When used in such a way, the other pump will charge a substrate to a full -VCC.
