Abstract
A technique for correcting for DC offset in a phase locked loop involves generating digital phase information in response to an input signal and then generating an offset correction signal in response to the digital phase information. The digital phase information may include transition samples that are integrated to generate the offset correction signal. Integrating the transition samples helps to compensate for the effects of phase noise, especially phase noise that is contributed by the input signal and/or the recovered clock signal.
