Abstract
Circuits, methods, and system for DC voltage conversion are disclosed. A charge pump circuit is described that includes input switches and output switches that are individually controlled by different clock signals to alternatively couple energy storage capacitors to an input and to an output. The individualized switching control allows for the use of clock signals with no overlapping transitions to improve conversion efficiency. Additionally, the input switches are controlled by clock signals that are level shifted relative to the input voltage. The level shifted switching control also improves efficiency and allows for a range in input voltages to be accommodated for DC voltage conversion.
