Title: Planar Electromagnetic Bandgap Structure for Wideband Switching Noise Mitigation in High Speed Circuits
With the increasing demand for modern digital circuit with fast edge rates and high clock frequencies, simultaneous switching noise has become a major concern. When many active devices switch at the same time, the switching noise generated can cause fluctuations or disturbances in the power distribution system (PDS) which, in turn, leads to a degradation of the signal integrity (SI). When this noise propagates…
