Investigating the global suppression of the power/ground plane noise

In this paper, the global suppression of the power/ground noise induced by a transient current on vias within a parallel-plate power distribution system is studied. Two different methods of noise suppression, i.e. differential via routing and application of an electromagnetic bandgap (EBG) structure, are investigated. The latter offers noise suppression in all azimuthal directions, while the noise suppression achieved by differential routing depends on the location of the observation point and improves at farther distances from the source.
