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.

Impedance is the most fundamental and important electrical property of any component. With a very simple technique, anyone can simulate the impedance of any circuit in seconds using any version of SPICE, for free. Read on to learn more.

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.

In the January 2021 print issue and the April 2021 online issue of the Signal Integrity Journal, I wrote an editorial in which I threw down a gauntlet to tool vendors to offer low cost or free versions of their tools to help engineers accelerate up the learning curve. Ansys picked up that gauntlet and now offers a free version of their industry standard electromagnetic simulator suite, Electronics Desktop. 

Fans of a single, multifunction instrument that replaces a dozen benchtop instruments will be excited with the release from Liquid Instruments. Here’s a closer look at this multi-function instrument that combines the features of a bench top full of instruments, like a scope, a DMM, a function generator, a frequency response analyzer, a spectrum analyzer, and even an impedance analyzer, all into one USB controlled instrument. 

Eric Bogatin has a little fun with engineering in this tongue-in-cheek celebration of EE jargon; don’t forget your flux capacitor!

SIJ Technical Editor Eric Bogatin reviews two webinars: one on additively manufactured electronic circuits and one on automotive circuits.

The conventional PCB fabrication process for printed circuit boards is subtractive. Averatek recently introduced a new chemistry technology making semi additive circuit board fabrication more attractive for ultra fine line applications. SIJ’s technical editor, Eric Bogatin, takes a closer look.

There is an unsatisfied thirst by professional engineers to play with tools that give them a taste of the pro-level tools. Eric Bogatin makes his argument for low cost or “student level” equipment from tool vendors.

Following best design practices for controlling EMI will increase your chance of success in your next design. But, sometimes knowing what not to do is just as important.
