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.
