摘要

本文基于台积电22nm CMOS工艺，设计了工作频率为50MHz的电荷泵。为了进一步扩大充电放电时CP电流匹配的输出电压范围，提出了一种基于低压差动电流镜技术的CP结构。采用轨对轨运算放大器对电压进行箝位，提高了充电电流和放电电流的匹配精度。

Design of Charge Pump with Low Voltage Differential Current Mirror in 22nm CMOS Technology

In this paper, based on TSMC 22nm CMOS process, a Charge Pump with a working frequency of 50MHz is designed. In order to further expand the output voltage range with current matching of CP when charging and discharging, a CP structure based on low voltage differential current mirror technology was proposed. Rail-to-rail operational amplifier is used to clamp the voltage and improve the matching accuracy of charge current and discharge current of CP.
