Broadband suppression of simultaneous switch noise (SSN) using Z-Bridge Planar Electromagnetic Bandgap power distribution network for Ultra Wide Band (UWB) application

This paper proposed a Z-Bridge Planar Electromagnetic Bandgap (ZP-EBG), which can effectively suppress simultaneous switching noise (SSN), and can be used in UWB application. Using the Z-bridge with slot or meander line to improve the bandgap. 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, compare with solid reference power plane and conventional UC-EBG, respectively.
