摘要：

针对使用标准CMOS技术实现的传统电荷泵输出电压较低的不足,文中提出将基本的电荷转移开关进行改进的MOS电荷泵,在泵送增益增加电路的基础上,通过在泵的输出级增加第3个控制信号来提高电荷泵的电压增益,以得到更高的输出电压,将其作为无线传感器的能量收集电路。仿真结果表明,该改进型电荷泵电路适合于低电压设备,并具有较高的泵送增益。其输出电压在同类电荷泵中最高,在1.5 V电源条件下,可高达8.5 V。

Abstract:

Due to the disadvantages of traditional charge pump for low output voltage using standard CMOS technology,the paper proposes a new basic charge transfer switch to improve the performance of MOS charge pump,based on pumping gain increasing circuit,the voltage gain of the charge pump can be improved by adding a third control signal at the output stage of the pump.In this paper,we use it as an energy wireless sensor circuit to produce a higher output voltage.The simulation results show that the improved charge pump circuit for low-voltage equipment has a high pumping gain.The output voltage (up to 8.5 V at 1.5 V) is higher than that achievable by any other charge pumps.

Key words: MOS charge pumps;charge transfer switches;higher output voltage;energy harvesting
