  • Method of static phase offset correction for a linear phase detector
    Patent number: 8948332
    Abstract: A method for calibrating a clock and data recovery circuit may include configuring a phase detector as a bang-bang phase detector. The bang-bang phase detector may be used to determine a phase difference between a sampling clock provided by an interpolator and a calibration signal. The phase detector may also be configured as a linear phase detector. While using the linear phase detector, a linear phase detector parameter may be adjusted such that the phase difference between the calibration signal and the sampling clock is zero, while keeping the phase of the sampling clock fixed.
