Abstract: This application discusses, among other things apparatus and methods for a voltage boost circuit. In an example, a voltage boost circuit can include first and second inverters, sharing a first supply node, and sharing a second supply node, a first charge transfer capacitor, configured to couple a first clock signal to the first inverter output, a second charge transfer capacitor, configured to couple a second clock signal to the second inverter output, the second clock signal being out-of-phase with the first clock signal, a first gate drive capacitor, configured to couple the first clock signal to the second inverter input, and a second gate drive capacitor, configured to couple the second clock signal to the first inverter input.

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.
