In high-speed circuit designs, power integrity (PI) and electromagnetic interference (EMI) are connected together. When the edge of the cavity created by power (PWR) and ground (GND) planes in PCBs radiates, the peak frequencies in the emissions are the same as the peak frequencies in the cavity self-impedance.

My aging vibration system started faulting. Shaking for 30 years takes a toll on a thing, after all. The system is pretty straightforward, just a big stack of audio amps and a controller. Much to my lab manager’s chagrin, I had been intentionally ignoring the warning signs.

The power electronics engineer and the power integrity engineer share a common goal: provide the system with the correct voltages, currents, and noise characteristics to achieve the desired performance. Unfortunately, they do not share much else. They generally use different tools, vocabulary, and figures of merit. As a result, both sides lose.

In exploring options to demonstrate ringing from reflections in transmission lines, Professor Eric Bogatin gets a greater understanding of debouncing circuits. Read on to see where his investigations led him.

Ken Willis provides some background on the IBIS AMI standard and looks ahead to what’s next.

Rohde & Schwarz has always been known for high end, very accurate instruments in the high frequency but did you know that R&S has a portfolio of value class instruments with more than 100 products and 300 accessories? From their recent release, here is a summary of the new value instrument additions they highlighted.

Eric Bogatin explores just how much better the sine wave is from a more expensive function generator compared to the lower cost units. He asks the question: Just how much bang do you get for your buck? Read on to see how he does it.

Ransom Stephens describes himself as physicist, author and technologist. Add life coach to that list, which he aptly played delivering one of the two keynotes at the Electronic Design Innovation Conference (EDI CON) last week in Santa Clara. Titled “Innovation, Incorporation, and Integrity,” Stephens riffed on why we work and not losing sight of our values and calling.
