摘要
该文设计采用SMIC1．2V，0．13μmCMOS工艺。通过对电荷泵的非线性特性分析，设计一种低电压，高性能的电荷泵电路。这种电荷泵电路上下支路的电流失配在300mV-900mV的输出摆幅下得到很好的优化，与传统低压结构比较有明显优势，同时设计中也抑制了电荷共享等电学失配。
This paper describes a CP （charge pump） for PLL （phase locked loop） by SMIC 1.2V, 0.13 μm CMOS process. This proposed circuit, as a high performance ,low voltage and perfect currents match circuit, which is based on analyzing nonlinear character of CP. It has good optimum mismatch when output is between 300m V- 900m V, it has better performance than conventional structure, reducing electrical mismatch such as charge sharing is also as a part of the design consideration.
