Abstract

A hybrid high-voltage regulating charge pump is proposed for point-of-care electrokinetic concentration chip applications. The hybrid charge pump is composed of three cascaded sub-pumps. High efficiency, minimized area, wide output current range, and high regulated output voltage are achieved by selecting charge pump architectures that provide high voltage conversion gain with less number of stages. The proposed charge pump is designed and fabricated in 180 nm BCD process. Simulation results show that the proposed system provides a maximum efficiency of 48.26%, while providing a maximum output voltage of 65 V.
