ABSTRACT:
Systems and methods for synchronization of clock signals are disclosed. In a feedback system such as a delay-lock loop circuit, delays to be applied can be determined adaptively based on a phase difference between a reference signal and a clock signal being delayed. Such adaptive decisions can be made during each feedback cycle, thereby making it possible to achieve a phase lock faster and more efficiently. In some embodiments, such adaptive functionality can be incorporated into existing circuits with minimal impact.
