ABSTRACT:
A charge pump provides a programmable multiplication factor for generating an output voltage. A first output voltage may be generated by connecting a first plurality of N capacitors in a first plurality of (N+1) configurations. A second output voltage may be generated by connecting a second plurality of M capacitors in a second plurality of M+1 configurations. The first plurality of N capacitors and the second plurality of M capacitors have one or more capacitors in common. The integers M and N may be equal, although this is not required. The first plurality of configurations is different than the second plurality of configurations, thereby providing different multiplication factors for the first and second pluralities of configurations. In one embodiment, the first plurality of (N+1) configurations results in an output voltage of about 3/4× an input voltage.
