Abstract :
The effect of EBG structures in various noise source environments is investigated. In this paper a one-dimensional electromagnetic band gap structure (1D-EBG) has been used in the power/ground planes for isolating signal vias from noise sources. The 1D-EBG structure generates about -70dB isolation in the path between the noise source and the signal via structure, so as to minimize the coupling of the power/ground cavity noise into the signal lines. In the presence of EBG structures, the voltage noise and timing jitter are significantly reduced for periodic noise sources. However, for random noise sources, the voltage noise and timing jitter can increase in the presence of EBG structures. This paper quantifies this effect
