摘　　要：采用电荷泵电路实现电压倍增的原理,设计出一种新型正负倍压双输出电荷泵电路,该电路可以将+5 V电源输入转换为广泛应用于接口电路中的±10 V电源电压,尤其适用于无法使用到±10 V电源的场合.该设计采用6μm铝栅工艺库对该电路进行了仿真,其仿真结果与理想值基本一致.Adopting the basic principle of double voltage implemented by charge pump circuit, a novel double output charge pump circuit for double voltage is designed. The circuit can convert voltage from ＋ 5V to ±10 V, which is always used in some interface circuits widely, and it is suitable to some certain circuits that used at the voltage of ± 10 V, but is difficult to get. The circuit of charge pump is simulated with 6 μm process, and the obtained result consists with ideal one.
