The IEEE P370 standards group was formed over four years ago to draft a standard for the Electrical Characterization of PCB interconnects up to 50 GHz. On Monday, Jan 30, 2018, more than 30 engineers attended the organization’s first “plug fest” at the Santa Clara Convention Center to exercise some of the features of the proposed standard.

Blando’s presentation illustrates the value of never accepting a result if it is not consistent with your engineering judgement. The determination of Blando’s team to resolve this simple problem benefits all of us to enable better differential pair measurements.

In our first electrical engineering class, we learn that the voltage across an inductor is L di/dt. We are ingrained with the idea that the voltage across an inductor is generated by the changing current through it. Not so, says Larry Smith, industry Power Integrity expert from Qualcomm and member of the SIJ EAB.

I’ve been attending and presenting at DesignCon for 28 years since the first HP High Speed Digital Symposium. And every year, it’s been the same thing, overloaded with too many great talks, too many companies’ latest products to see and too many online friends to finally meet in person. The only thing that has changed is the “too many” part. Needless to say, the many part has only increased.

We’ve come to the end of our first complete year of online publication. Our Editorial Advisory Board (EAB) has done a superb job of nudging us in the right direction, contributing high value technical pieces and reviewing all the technical content submitted to the Signal Integrity Journal. As a final passing favor to the SI, PI and EMC community of readers, we want to leave all of our readers with a year-end holiday gift.

Not an official award, per se, but Eric Bogatin gives his top pick for his favorite demo at the recent EMC event in Washington DC.

Traditional swept-tuned EMI spectrum analyzers and step-tuned EMI receivers may produce misleading or entirely false measurement results when the signal under study is not steady state, but transient. See Eric Bogatin's review of a demo by Lee Hill on this subject.

Ground is NOT a current return path. Read on to see Todd Hubing’s four rules of effective grounding strategy.
