Abstract
Apparatus and methods that have a semiconductor charge pump can be implemented in a variety of applications. Such a charge pump can have a charge pump unit core that includes a pump section and a single passgate coupled to the pump section to transfer charge, where the single passgate is a n-channel metal-oxide semiconductor (NMOS) transistor coupled directly to an input and an output of the charge pump unit core. The transfer of charge can be based on a set of clock signals. Additional apparatus, systems, and methods are disclosed.
