摘要

Simultaneous switching noise,also known as ground bounce noise or parallel plate waveguide noise is one of the major concerns for high-speed digital computer systems with fast edge rates,high clock frequencies,and low voltage levels. The resonance modes between the power/ground planes excited by the noise causes significant signal integrity problems as well as electromagnetic interference issues. In the present paper a novel power plane designed with triangle patches and hexagonal array will be proposed which provide noise suppression over a wide band frequency range. The proposed structure is based on the two-layer concept with designing a periodic coplanar splitting pattern on the power plane and still keeping continuous for the ground plane. Although the proposed power plane demonstrates wideband noise suppression with a cost effective design,the degradation of the perforated plane to the signal integrity is needed to be evaluated,since it could affect the signal quality. A single-ended signal layer will be modeled in the equivalent electromagnetic model and eye diagrams,TDR and S-parameters will be used to evaluate the signal integrity of the structure (with splitting plane) in comparison with the case of continuous power plane.
