Journal ArticleDOI
Removable EBG-Based Common-Mode Filter for High-Speed Signaling: Experimental Validation of Prototype Design
Michael A. Varner,Francesco de Paulis,Antonio Orlandi,Sam Connor,Michael Cracraft,Bruce Archambeault,M. Hilmi Nisanci,Danilo Di Febo +7 more
TL;DR: In this article, a commonmode filter structure based on planar electromagnetic bandgap (EBG) technologies is designed, fabricated, and measured, which can be easily removed and substituted by another one that is designed to filter a different frequency.
Journal ArticleDOI
EBG-Based Common-Mode Stripline Filters: Experimental Investigation on Interlayer Crosstalk
F. de Paulis,Michael Cracraft,Carlo Olivieri,Samuel Connor,Antonio Orlandi,Bruce Archambeault +5 more
TL;DR: In this article, a filter based on EBG cavities employed for reducing common-mode currents along differential stripline traces is proposed, where the EBG cavity acting as a coupling path is accurately quantified.
Journal ArticleDOI
EBG-Based Common-Mode Microstrip and Stripline Filters: Experimental Investigation of Performances and Crosstalk
Francesco de Paulis,Michael Cracraft,Danilo Di Febo,Muhammet Hilmi Nisanci,Sam Connor,Bruce Archambeault,Antonio Orlandi +6 more
TL;DR: In this article, the authors analyze from a modeling and experimental point of view the filter effectiveness and the crosstalk among signal traces crossing the same commonmode filter based on electromagnetic bandgap structures in modern server design configurations.
Journal ArticleDOI
Reduction of EMI Due to Common-Mode Currents Using a Surface-Mount EBG-Based Filter
Qian Liu,Sam Connor,Carlo Olivieri,Francesco de Paulis,Antonio Orlandi,Michael Cracraft,Bruce Archambeault,Victor Khilkevich +7 more
TL;DR: In this article, two new commonmode (CM) filter structures were designed, fabricated, and measured, which are placed on the top of the PCB as a surface-mount component, instead of being implemented within the PCB stackup.
Proceedings ArticleDOI
Analytical PDN voltage ripple calculation using simplified equivalent circuit model of PCB PDN
Biyao Zhao,Chenxi Huang,Ketan Shringarpure,Jun Fan,Bruce Archambeault,Brice Achkir,Samuel Connor,Michael Cracraft,Matteo Cocchini,Albert E. Ruehli,James L. Drewniak +10 more
TL;DR: In this article, a physics-based circuit model extracted from the cavity model approach was used to calculate the input impedance seen by the IC looking into the printed circuit board (PCB) power distribution network (PDN) design performance.
