摘要
A method and apparatus for linearizing a phase locked loop (PLL) are provided. To accomplish this, three separate signal (two feedback/one reference or two reference/one feedback) are applied to two phase/frequency detectors (PFDs). Either an edge of the one reference signal or one feedback signal is approximately equidistant between corresponding edges of the two feedback or two reference signals so that the PFDs can properly apply actuation signals to a charge pump that account for jitter. Thus, a more linear PLL is provided.
