As rated by attendance, here are the Top 5 Webinars on SIJ of all time. These presentations are available to watch on demand at your leisure. Thank you for continuing to join us, as we look forward to bringing you many more educational and informative presentations in 2022 and beyond!

Now that I am teaching full time and have a number of undergraduate and graduate students doing weekly project reviews, I listen to more presentations than I give. I find myself giving the same feedback over and over again. So, I thought I would share my eight most common comments and tips to engineers giving presentations.

This first post in a new blog series, Extreme Measurements, introduces how an extreme measurement is defined. Find out how your extreme measurement story can end up on SIJ!

“Over the years I’ve come to realize that, particularly in signal integrity, half-wave resonances are often the cause of ugly S-parameters. You can argue that any type of resonance would cause problems, and you would be right. However, half-wave resonances are easily formed in topologies.” This article summarizes observations from Gustavo Blando on the formation and mitigation of half-wave resonances, and includes an in-depth study on the topic in PDF format from the author.

SIJ editorial advisory board member Yuriy Shlepnev offers a comparison of three ways to visualize the same s-parameter data, identifying how to get the most information from a plot.

How well do statistical models predict the behavior of real-world systems?  How can we make predictions about the likeliness and severity of worst-case system behavior?  In this article, the authors explain how they used a function generator and oscilloscope to collect varying population sizes of measurement parameter results in order to investigate the accuracy of a statistical model's predictions.

While eye diagrams and eye masks are both useful, they each hide as much information as they reveal. Read on to see how to get the most out of them for your design.

Bends in PCB traces look like very basic, simple structures that are easy to simulate. Technically, one can do the analysis with any electromagnetic solver with sufficiently accurate port de-embedding capabilities. The reflections from a bend in fine-line, high-speed digital interconnects are relatively small and may not even be detectable with measurement. So, who cares? Read on to find out more.

SIJ recently caught up with Timothy Vang, vice president of marketing and applications for Semtech’s Signal Integrity Products Group about the company’s latest product for 50Gbps PAM4 5G front haul deployments, how signal integrity and RF/wireless design overlap, and what is next for the team at Semtech.
