Signal Integrity Applications of an EBG Surface

Signal Integrity Analysis of High Speed Interconnects In PCB Embedded with EBG Structures

This paper brings out a novel method for reducing Near end and Far end Crosstalk using Electromagnetic Band Gap structures (EBG) in High Speed RF transmission lines. This work becomes useful in high speed closely spaced Printed Circuit Board (PCB) traces connected to multi core processors. By using this method, reduction of -40dB in Near-End Crosstalk (NEXT) and -60 dB in Far End Crosstalk (FEX...

Curved uniplanar EBG structure for suppressed ground bounce noise and improved signal integrity in power planes

A novel wideband uniplanar electromagnetic bandgap structure with curved line bridges (C-EBG) is proposed to be used in power planes for suppressed ground bounce noise (GBN) and improved signal integrity. Compared with a conventional uniplanar electromagnetic bandgap structure with straight line bridges (S-EBG), the CEBG structure significantly increases the equivalent inductance with less spli...

Estimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power

Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...

On Vector Fitting Methods in Signal/Power Integrity Applications

Vector Fitting (VF) has been applied to reformulate traditional system identification techniques by introducing a partial-fraction basis to avoid ill-conditioned calculation in broadband system identifications. Because of the reliable and versatility of VF, many extensions and applications have been proposed, for example, the macromodeling of linear structures in signal/power integrity analyses...
