High-frequency phase/frequency detector with improved reset mechanism |
摘要 |
The present invention provides a method and an apparatus for generating a phase error signal from a reference signal and a feedback signal using a modified reset generation mechanism. An input circuit receives a reference signal and a feedback signal. A phase error detector circuit generates a phase error signal based on the reference signal and feedback signal. The input circuit is reset and, after a delay, the phase error detector circuit is reset. The delay is selected so that there is no jitter associated with the dead zone.
