Fast Digital Calibration of Static Phase Offset in Charge-Pump Phase-Locked Loops [PDF]
, 2011 Mismatches within the charge pump (CP) deteriorate the spectral perfor- mance of the CP-PLL output signal resulting in a static phase offset. Classical analog approaches to reducing this offset consume large silicon area and increase gate leak- age ...
