Offset cancellation of charge pump based phase detector |
摘要 |
A offset cancellation of charge pump based phase detector is disclosed. The methods and circuits disclosed cancel inherent with a phase detector and imbalanced charge pumps. The offset cancellation includes detecting the phase detector and the charge pump offset with a calibration signal and a reference voltage source, and applying a calibration current to cancel the phase detector and charge pump offset.
