Abstract

A novel technique for mitigating simultaneous switching noise propagation in high-speed printed circuit boards is presented. The proposed concept is based on etching complementary split-ring resonators (CSRRs) on only one metallic layer of the printed circuit board. By such topology, the electric field between the power planes can be suppressed. It is shown here that by concentrically cascading CSRRs, an ultrawideband suppression of switching noise from sub-GHz to 12 GHz is achieved. A prototype of the proposed concept was simulated, fabricated, and tested. Good agreement is observed between simulation and measurement. Moreover, electromagnetic interference radiation from such perforated boards is investigated. Finally, the performance of the proposed board with CSRRs is assessed through signal integrity analysis using eye diagrams and compared with a reference (solid) board.
