This paper details a methodology of using multiple Huygens Boxes on the coupling path to predict RFI/desense at early design stage in mobile devices—all with an aim to minimize the RFI.

The voltage regulator module (VRM) contributes system level noise in several ways. Power integrity (PI) engineers tend to focus on transient voltage noise related to high-speed dynamic current. Many PI simulators ignore the VRM noise and use an ideal resistor and inductor model to represent the VRM. This overly simplistic approach misses many potential system level issues.

Why does a low cost through-hole SMA have a lower bandwidth than a surface mount SMA? The answer will surprise you.

My friend Steve Sandler pointed out a major hurdle we face in power distribution design: power engineers (who design power converters) and power integrity engineers (who design system bypassing-decoupling networks) use different vocabulary, techniques, and requirements. To understand a little better how we got here, I want to start with a prediction I heard sometime in the early 90s at one of the conference keynote speeches: “In 10 to 20 years, computers will look like hairy steamy golf balls.” 

EDI CON Online, a new interactive event being held online September 10-12, 2019, has announced its line up of technical session speakers.

Architectural decisions depend on the ability to adequately analyze the link. This paper presents a methodology to model and evaluate the performance of both center and edge sampling schemes.

Interested in performance analysis for 100+ Gb/s per lane PAM4 interfaces? This paper takes a detailed look at high-speed serial link error propagation models and different Ethernet coding schemes as part of FEC performance analysis for 100/200/400 GbE systems with 100+ Gb/s per lane PAM4 interfaces.

Looking into advanced error code correction? Many techniques involve forward error correction. But what exactly is that and how does it relate to your design? Cathy Liu spells it out in this article.

Obtaining accurate measurement data requires either accurate knowledge and accounting for the probe and fixture influence OR calibration methodology to remove these effects prior to measurement.
