Abstract

A phase alignment architecture enhances the performance of communication systems. The architecture aligns a divided clock (e.g., in differential Inphase (I) and Quadrature (Q)) to a main clock, even at extremely high speeds, where skew variations of the divided clock are comparable to the main clock period. The improvement in phase alignment facilitates ultra high-speed communications.
