System and method for pre-skewing timing of differential signals

摘要

A circuit for skewing differential signals includes a coarse adjustment stage configured to receive a differential input signal having a true component and a complement component, the coarse adjustment stage configured to impart a first controllable delay to at least one of the true component and the complement component of the differential signal, and a fine adjustment stage configured to impart a second controllable delay to at least one of the true component and the complement component of the differential signal, the second controllable delay having a resolution different than a resolution of the first controllable delay, the first controllable delay and the second controllable delay providing a timing skew between the true component and the complement component of the differential signal.
