Embedded power plane with ultra-wide stop-band for simultaneously switching noise on high-speed circuits

摘要

An embedded band selective (EBS) power plane is proposed using the hybrid-cell periodic structure. Because the periodic connections of the unit-hybrid-cell select different frequency rejection bands, the proposed EBS power plane performs ultra-wideband suppression of the simultaneously switching noise (about 9 GHz) with on average, over 60 dB noise elimination. This excellent behaviour is both numerically and experimentally validated.
