| Popis: | A novel electromagnetic bandgap (EBG) structure is proposed to suppress the simultaneous switching noise in high-speed circuits. The proposed EBG pattern is etched on the power plane while the ground plane remains intact. The unit is composed of an S-bridge EBG embedded with a coplanar EBG. The proposed EBG structure possesses an ultrawide bandgap extending from 0.28 to 25 GHz when the suppression depth is -45 dB. A prototype of the proposed EBG power plane is fabricated and tested, and good agreement is achieved between the simulation and the measurement. |
