Abstract
A distributed phase-correction circuit is described. This distributed phase-correction circuit reduces jitter in a delay line by averaging edge delay through local feedback of signals internal to the delay line. In particular, the distributed phase-correction circuit includes a delay line with multiple cascaded first phase-alignment elements that each delay the input signal by a fraction of the period (i.e., that perform distributed phase correction) based on feedback signals from a second delay line.
