Abstract

See full text

A DC-to-DC voltage converter comprising a differential charge pump that utilizes a differential clocking scheme to reduce output electrical noise by partial cancellation of charge pump glitches (voltage transients), and a corresponding method of operating a differential charge pump. The differential charge pump can be characterized as having at least two charge pump sections that initiate charge pumping in opposite phases of a clock signal to transfer (pump) charge to storage capacitors. The differential charge pump is particularly well suited for implementation in integrated circuit chips requiring negative and/or positive voltages, and multiples of such voltages, based on a single input voltage.
