Abstract
In this paper, a self‐similar fractal electromagnetic band‐gap structure with “L‐Cross ” slots is proposed and designed in the power plane to suppress the ground bounce noise in high‐speed circuits. Both the simulation and the measured results with good agreement with each other show a low onset band stop frequency of 500 MHz and a broad stop band of about 4 GHz. When combining the structure with decoupling capacitor walls at the boundary of the power plane, a broadband GBN suppression from DC to 6 GHz can be obtained. © 2006 Wiley Periodicals, Inc.
