Suppression of SSN in High-Speed Circuits using 1-D EBG structure

Abstract

In modern integrated circuitry, the need for high-speed printed circuit board design is growing day by day, The high-speed circuits are exposed to noise generated due to fast edge rates, high clock frequency, and low voltage levels. Simultaneous switching noise (SSN) is a major issue in high-speed digital circuits that occurs due to the signal switching at a very fast rate between ground and power plane. The signal integrity issue can be reduced by proposed novel technique of electromagnetic bandgap structure. In this paper, the one-dimensional L-bridge EBG structure is proposed, The L-shaped bridge design not only widen the bandwidth of stop-band, but also enlarge the mutual coupling betwixt adjoining cells also this proposed structure focused on mitigation of noise in high-speed circuits. The simulation result achieves the wide range of band-gap from 2.56 GHz to 13.47 GHz at -30 dB and can obtain ultra-wide band suppression of SSN.
