“…According to the analysis above, a 1-D equivalent circuit model is developed for the traditional L-bridge [34]. The equivalent model consists of three parts: The first part describes the propagation characteristics between the EBG patch and the solid ground plane represented by the equivalent capacitance C p,l and inductance L p,l .…”

A selectively embedded method for enhancing the suppression against simultaneous switching noise is proposed based on coplanar electromagnetic bandgap (EBG) power plane. According to this method, a novel EBG structure is designed on the basis of periodic L-bridge, and meanwhile, a ML-bridge cell is inserted into each L-bridge unit where a power port is located. It is shown that the structure achieves an ultrawide bandgap extending from 490 MHz to 16 GHz at suppression depth of -30 dB by both simulation and measurement. In addition, the lower and upper cutoff frequencies are estimated by the use of equivalent circuit models and parallel-plate waveguide theory, respectively. In the end, the IR-drop characteristics over the structure are investigated.Index Terms-Electromagnetic bandgap (EBG), resonant cavity, signal integrity, simultaneous switching noise (SSN).

“…A CM filter is developed in [9] taking into account the inductance and capacitance provided by the repetitive photonic bandgap structures, and in [16], the filter is based on the modulation of the signal lines physical dimensions. Moreover, the CM filtering property in [4]- [8] and [10]- [15] is based on the resonances of the EBG cavity (formed by the continuous reference plane and the patterned EBG one). In [17]- [20], the EBG cavity transfer function is described, whereas the EBG performance validation through the model-to-hardware correlation is presented in [21]- [24].…”

The aim of this study is to analyze from a modeling and experimental point of view the filter effectiveness and the crosstalk among signal traces crossing the same common-mode filter based on electromagnetic bandgap structures in a modern server design configurations. Both microstrips and striplines are considered in the study, detailing the differences among them in the design step as well as in filter geometry and response. Simulation models and experimental setups are carefully described, and the numerical and measurement results are compared and discussed.

“…Solid-type VDD plane is ordinarily used for most of PCBs. Recently, an electromagnetic band-gap (EBG)-type VDD plane is proposed to be effective to suppress radiated emission for mixed-signal applications or high-speed digital applications [1]- [3]. In particular, insulator thickness and onboard capacitors placed on a whole area of PCB are design parameters to determine the power supply impedance of power/ground plane.…”

The relationship between S21 properties and far-field radiated emission has been experimentally characterized for various types of power bus structures. As design parameters of power bus structures in printed circuit boards, the effects of VDD plane configuration, insulator thickness between VDD plane and ground plane, on-board capacitors, and signal routing were investigated. First, S21 properties of solid and electromagnetic band-gap (EBG) -type VDD planes were measured for both with and without on-board capacitors. Then, far-field radiated emission was measured for the combination of these design parameters. On-board capacitors induced stop-band in the low frequency range. It has been found that high level of far-field radiated emission was excited at the almost same frequencies of S21 peaks.
