Abstract-Simultaneous switching noise (SSN) is a significant problem in high-speed circuits. To minimize its effect and improve the electrical characteristics of circuits such as signal integrity (SI) and power integrity (PI), a novel power plane with planar electromagnetic bandgap (EBG) structure is proposed for SSN suppression in printed circuit boards (PCB) in this paper. In which a kind of improved long bridge is used and the equivalent parallel inductance can be increased significantly. Compared to the typical spiral bridge EBG structure with the same parameters, the long bridge EBG structure will change bandgap into dual-band, with lower center frequency and wider bandwith. The effectiveness and accuracy of this structure are verified by both simulations and measurements.

SUMMARYNoise coupling on the power distribution networks (PDN) or between PDN and signal traces is becoming one of the main challenges in designing above GHz high-speed digital circuits. Developing an efficient and accurate modeling method is essential to understand the noise coupling mechanism and then solve the problem afterwards. In addition, development of new noise mitigation technology is also important for future high-speed circuit systems. In this invited paper, a novel modeling methodology that is based on the physics-based equivalent circuit model will be introduced, and an example of multiple layer PCB circuits will be modeled and validated with good accuracy. Based on the periodic structure concept, several new electromagnetic bandgap structures (EBG), such as coplanar EBG, photonic crystal power layer (PCPL), and ground surface perturbation lattice (GSPL), will be introduced for the mitigation of power/ground noise. The trade/offs of all these structures will be discussed.

“…Later they start to be considered as a simple and easy-to-design approach to be implemented in PCBs for SSN rejection in the GHz range, where usual techniques for power bus decoupling, i.e., bypass capacitors, are not effective [16]. Many contributions have been proposed for designing EBG geometries to reduce noise propagation within the power planes in PCB and packages [17][18][19][20][21]. They have been studied also as a simple way to reduce the common mode noise current and thus unwanted radiation from PCBs [22][23][24][25].…”

Abstract-Noise reduction in PCB is a major concern in the present digital electronic systems with data rate beyond 10 Gbps. The noise, due to simultaneous switching noise, radiation from signal vias crossing the planes, etc. can propagate within parallel plane cavity at its resonant frequencies, thus allowing coupling between integrated circuits (ICs) far from each other. Electromagnetic band-gap (EBG) structures are largely employed as noise reduction technique. This paper presents a quick and efficient analytical approach for evaluating the EBG noise reduction performances in terms of band-gap limits. The study is based on the physics behavior of the planar EBG structures, focusing on its resonant properties. The resonant modes of the EBG cavity are affected by the additional inductance of the patterned plane respect to the case of the ideal solid plane cavity. The formulas provided, based on the quantification of such inductance, can be easily implemented and employed for a quick layout design of power planes in multilayer PCBs, as shown in a practical example of a partial EBG plane.
