Conventional CMOS charge-pump circuits havesome current mismatch problems. The current mismatch induces a phase offset which deteriorates the performance of Up PLLs or DLLs. This paper investigates causes of current mismatch of conventional CMOS charge-pump and proposes new charge-pump circuits to reduce the current mismatch. The Vpb DLL with proposed charge-pump is simulated in a 0.18 um CMOS process.
