All-digital delay-locked loop tuning method with randomized LSB-tuning

摘要

In some example embodiments, there may be provided an apparatus. The apparatus may include a delay line including a plurality of cells; and tuning circuitry coupled to the delay line and configured to generate a first output and a second output to tune the delay of the delay line, wherein the first output tunes in aggregate the plurality of cells of the delay line, and wherein the second output tunes each of the plurality of cells separately. Related methods, systems, and articles of manufacture are also disclosed.
