一种新型低电荷共享电荷泵电路

A New Kind Of Charge Pump With Low Charge Share

采用GSMC0.18μm工艺设计了性能优良的电荷泵,与传统电荷泵相比,此电荷泵具有低失配(mismatch≤2%)、低功耗(≤0.15mw)、低电荷共享的特点,可广泛应用于电荷泵锁相环(CPPLL)中。

GSMC0.18 μm process is used to design a new charge pump with good performance, comparing charge pump, this one has the characteristics of low mismatch（24%）,low power comsumption（1.5mw） charge share, it can be widely used in cppll.
