METHODS AND APPARATUSES FOR DELAY-LOCKED LOOPS AND PHASE-LOCKED LOOPS

摘要

A low power delay-locked loop (DLL) is presented. In one embodiment, the DLL includes a phase detector which includes a reference input and a feedback input to determine a phase difference. The DLL also includes a controller to determine whether to provide a signal to both the reference input and the feedback input such that the reference input and the feedback input receive an identical input, for example, during low power operation.
