Abstract
A technique for distributing common phase clock signals is disclosed. In one embodiment, the technique is realized by providing a forward traveling wave signal and a reverse traveling wave signal on a transmission line, wherein the forward traveling wave signal and the reverse traveling wave signal each have a common frequency and a constant relative phase. The forward traveling wave signal and the reverse traveling wave signal are each tapped off the transmission line at a plurality of different locations along the transmission line. The forward traveling wave signal and the reverse traveling wave signal that are tapped from the transmission line at each of the plurality of different locations are then combined so as to form a corresponding plurality of clock signals each having the common frequency and a common phase.
