Abstract
A high efficiency CMOS charge pump suitable for low voltage applications is proposed. To improve the pumping efficiency, the charge pump circuit employs a novel charge transfer switch (CTS) control scheme which combines the backward control scheme with the forward control scheme. In 130 nm CMOS process, the simulation results have shown that the proposed charge pump has higher pumping efficiency compared to other charge pumps.
