文章提出了一种基于Dickson原理的电荷泵电路,采用齐纳管作为开关器件。该电路克服了采用MOS管作为开关器件的Dickson电路在多级级联时的转换效率急剧下降问题,并且可以利用齐纳管来稳定输出电压。Spice仿真结果显示,五级齐纳电荷泵可以轻松在3V电源电压下实现10V左右的稳定电压输出。该电路结构简单,与标准CMOS工艺兼容,具有较高的应用价值和经济价值。

A charge pump use zener diodes as switch devices is presented, which is based on Dickson charge pump. Degradation of transform efficiency which occurs at stack Dickson while using MOS devices as switch devices is fixed in this circuit, Furthermore, zener diodes are used to stable output voltate. Spice simulation shows that five-stage Diskson use zener switch can offer 10V stable output while power voltage is 3V. Structure of this circuit is simple and compatible with standard CMOS process,
