Abstract
An apparatus for transferring charge has a first charge pump path with a plurality of stages having first capacitors, and a second charge pump path, also with a plurality of stage having second capacitors, in parallel with the first charge pump path. The first and second charge pump paths are coupled to share a common output node. The apparatus also has a timing circuit coupled with the first and second charge pump paths. Among other things, the timing circuit is configured to cause at least one of the first capacitors to periodically charge at least one of the second capacitors.
