A subregional embedded electromagnetic bandgap (EBG) structure for suppressing simultaneous switching noise (SSN) is proposed by analyzing the SSN suppression mechanism. In this paper, a novel EBG structure is designed on the basis of periodic L-bridge, while, a small middle L-bridge (SML-bridge) cell with reverse meander line is embedded into each L-bridge unit. The L-bridge unit is divided into two regions. It is shown that the SML-bridge cell achieves an ultrawide bandgap extending from 380 MHz to 10 GHz at the suppression depth of -30 dB by both simulation and measurement. SML-bridge cell external is verified to meet signal integrity (SI) by the time-domain simulation. In addition, the conclusion for the noise suppression effect is estimated by equivalent circuit models and parallel-plate waveguide theory. Furthermore, the IR-drop and the dc resistance are accurately investigated by the simulation. Eye patterns are generated for analyzing the SI compared with the traditional L-EBG plane.
