Abstract

To build a stable power distribution network for high‐speed digital systems, simultaneous switching noise (SSN) in multilayer PCBs and packages needs to be sufficiently suppressed. In this article, a novel triangular‐type uniplanar compact electromagnetic band‐gap with different bridges designed for power/ground planes is proposed for the ultra‐broadband suppression of SSN. The SSN suppression performance of the proposed structure is validated both numerically and experimentally. A −30 dB suppression bandwidth for SSN is achieved starting at 800 MHz and extending to 15 GHz and beyond, that is, almost the entire noise band. © 2009 Wiley Periodicals, Inc.
