Abstract :
In this paper, we propose a localized spiral-shaped EBG structure which can effectively suppress simultaneous switching noise (SSN) when the power plane drives high-speed ICs on a small area. Also we present a new technique to greatly improve resonance notch in a stopband by utilizing λ/4 open stubs in a conventional periodic EBG power plane. Numerical simulations are performed using commercially available 3D electromagnetic field simulator for both proposed structures. The results show they have better performance for SSN suppression, compared to conventional periodic EBG structures.
