ABSTRACT:
A high efficiency charge pump for low and wide voltage ranges. The charge pump includes main and secondary charge pumps, the secondary charge pump is employed to avoid the Vt.sub.N drop that the main charge pump exhibits. The secondary charge pump allows the main charge pump to pump to a theoretical maximum of 2 VCC, while maintaining an efficiency close to 40%.
