John McCloskey spent almost half of his career working on the JWST. Along the way, he recorded his experiences, bringing the rest of the world along on a whirlwind journey to witness the thrills, tensions, and feats of engineering that went into his success.

Ideal circuit elements are a powerful tool that enables us to explore the real world in virtual prototypes. Engineers can often gain insights and reach an optimized design faster using a virtual prototype than would be possible when building a real physical prototype.

Eric Bogatin shares four useful tools that illustrate the dynamic nature of propagating signals, promoting the understanding that is imperative to the design of high-performance products.

In just two generations, six different technological revolutions have transformed our economy, our careers, and our quality of life, for better or for worse. Eric Bogatin reflects upon industry progress and explores the potential impact of the latest development in technological innovation, generative AI.

With summer upon us, it’s time to catch up on the webinars we might have missed in the last year. Here is a viewing list of the high value video content I will be reviewing in this column over the summer.

Eric Bogatin takes a closer look at the potential consequences of the widening gap between industry demand and the supply of engineers with signal integrity design skills, and poses potential solutions to inspire future generations of signal integrity engineers.

In this article, Eric Bogatin uses the issue of power integrity to illustrate why dialog between experts is crucial. 

About 150 years ago the first stable transatlantic cable was laid and messages were sent between Ireland and Newfound­land over copper. The data rate on this cable was not even 1 bit/sec, it was 0.1 bit/sec. Concerns over the cable reliabil­ity and the slow data rate led some to believe copper was doomed as a communication media for these long cables.

If you’ve just started on the path of designing high-speed serial links or have designed dozens of your own, Don Telian’s Signal Integrity in Practice is the book that will accelerate your engineering judgment and possibly save you from multiple design spins. Eric Bogatin takes a closer look at what he considers a must-have book for new and experienced engineers.

Who doesn’t love an easy-to-use 2D field solver to calculate the single-ended or differential impedance of PCB transmission lines? Eric Bogatin takes this one from Sierra Circuits for a test drive.
