Abstract: One Z-Bridge Planar Electromagnetic Band-gap (ZP-EBG) is proposed, which can effectively suppress simultaneous switching noise (SSN), and can be used in high speed digital application. The Z-bridge with slot or meander line is used to improve the band-gap. The simulation and measurement results indicated that suppression bandwidth is broadened from 280MHz to 15 GHz. From the time domain simulation, the proposed ZP-EBG can efficiently isolate the SSN over 95% and 90%, comparing with solid reference power plane and conventional UC-EBG, respectively. Differential signal is proposed to decrease the influence on the signal integrity. In addition, the ZP-EBG is simple and can be easily designed and fabricated using a standard PCB, resulting in a low-cost process. So it can be a good power plane candidate in mixed signal circuit application.
