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.

Now in its fourth generation, which sports data-transfer rates up to 16 Gb/s, Peripheral Component Interface Express standard (PCI Express, or PCIe) requires challenging physical-layer test requirements (Figure 1). We've covered electrical compliance test for PCIe 3.0 in some detail, but with the test specifications for PCIe 4.0 rounding into shape, it's time for a deep dive into electrical compliance test for this ubiquitous peripheral interface protocol.

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.

Selecting printed-circuit-board (PCB) materials that support modeling with modern computer-aided-engineering (CAE) simulation software and help achieve excellent signal integrity (SI) for high-speed digital circuits usually starts with key material parameters, such as dielectric constant or Dk.

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.

As rated by reader views, here are the Top 10 Articles on Signal Integrity Journal for 2017. Thank you for your readership in 2017, and we look forward to bringing you many more great technical features in 2018!
