Abstract
A circuit for use in a phase lock loop including a first phase detector to detect a first phase error between input signals, the first phase detector obtaining the first phase error during a first time period, a second phase detector to detect a second phase error between the input signals, the second phase detector obtaining the second phase error during a second time period, the second time period being longer than the first time period, and a compensation circuit to compensate the first phase error with a portion of the second phase error signal.
