Abstract:

A new ultra-wideband electromagnetic bandgap (EBG) structure is proposed for simultaneous switching noise suppression (SSN). A analysis and design of the bandgap properties of the new EBG structure is given, the characteristics of stopband and signal integrity are simulated, showing that the new EBG's stopband is improved, and the lower cut-off frequency is decreased comparing with the Z-bridged EBG structure with the same parameters. Meanwhile, signal integrity of the proposed EBG power plane can be improved by using differential transmission lines.

Key words: simultaneous switching noise; electromagnetic bandgap; signal integrity, electromagnetic compatibility
