设计了一种应用于低压,高效率快速启动四相时钟电荷泵。该电荷泵利用少量辅助晶体管,在启动阶段将电荷注入升压电容中,降低了电荷泵启动时间。设计了一种新型四相时钟电路,降低了时钟驱动功耗,提高了效率。在1V的电源电压,0.13um工艺下,仿真结果显示,在四级结构下,四相时钟电荷泵的效率高达81%,相比传统四相时钟电荷泵结构,启动时间减少了10%。

A high efficiency four-phase clock charge pump for low pressure is designed.The charge pump use a small number of auxiliary transistors to inject the charge into the booster capacitor during the start-up stage,which reduces the start-up time of the charge pump.A novel four-phase clock circuit is designed to reduce the power consumption and improve the efficiency.Under the 1V power supply voltage and 0.13um process,the simulation results show that under the four-stage structure,the efficiency of the four-phase clock charge pump is as high as 81%.Compared with the traditional four-phase clock charge pump structure,the start-up time is reduced by 10%.
