A Digital Calibration Technique for Charge Pumps in Phase-Locked Systems

A digital technique is adopted to calibrate the current mismatch of the charge pump (CP) in phase-locked systems. In this digital calibration technique, there is no extra replica CP needed. In addition, it can calibrate the CP under different control voltages on the loop filter to be immune to the c...
