POWER DISTRIBUTION NETWORK FOR IMPROVING SIGNAL QUALITY BY MINIMIZING THE INFLUENCE OF A DISCONTINUOUS REFERENCE SURFACE

摘要

PURPOSE: A power distribution network is provided to minimize the influence of a discontinuous reference surface on signals by forming a return current path for a signal line.;CONSTITUTION: A power distribution network has a reference surface which has a discontinuous structure and is arranged under a signal line and a return current path which is formed in the reference surface for the signal line. The return current path is formed in one of identical, proportional, and enlarged shapes relative to the signal line. The reference surface is formed into either a power source surface or a grounding surface, having a discontinuous structure in a printed circuit board or package. The discontinuous structure is a single-side electromagnetic bandgap structure.;COPYRIGHT KIPO 2012
