摘要
A novel z-bridged electromagnetic bandgap power plane is proposed for ultra-wideband suppression of simultaneous switching noise (SSN) in high-speed digital circuits. The z-shaped bridge effectively increases the inductance between two adjacent unit cells. Stopband of -30 dB is realized from 260 MHz to 6.76 GHz. The excellent SSN suppression performance is validated both numerically and experimentally; good signal integrity performance can be obtained by using differential transmission lines.
