A novel approach for the suppression of the parallel-plate noise in high-speed circuits is proposed by utilizing a metallic electromagnetic band-gap (EBG) structure. The key idea relies on replacing one of the two solid electric conductor plates with a metallic EBG surface of compact texture. To validate the concept, an EBG surface was fabricated and employed in a number of via-containing parallel-plate test boards. Frequency domain measurements showed a band-gap of about 1.7 GHz around 3.77 GHz. More importantly, suppression of the parallel-plate noise by 65% was achieved based on time domain reflectometry experiments.read more
