Abstract
ABSTRACTA novel swapped double-sided electromagnetic bandgap (DS-EBG) power/ground plane is proposed with broadband suppression of the simultaneous switching noise (SSN) and low radiation emission. By using the double-sided structure, the equivalent inductance between the EBG cells can be well improved and result in the broadband suppression of SSN. In the proposed structure, pairs of via are used to build the three-dimensional bridges between the swapped power/ground planes. They also lead to the suppressions of SSN be improved. Simulated and measured results show good agreements with each other. Additionally, the measured radiation emission of the proposed structure shows that it has lower electromagnetic interference compared with the two typical reference boards.
