Signal Integrity Journal

Signal Integrity Journal (SIJ) is a companion publication to Microwave Journal, focusing on topics such as signal integrity, power integrity, and electromagnetic compatibility/interference (EMC/EMI). It features a range of content including industry news, technical articles, white papers, product information, a Buyer’s Guide, webinars, videos, and much more. SIJ stands out as the sole peer-reviewed journal dedicated to these areas of the industry. Initially launched as a website at www.signalintegrityjournal.com, it expanded to include a magazine format in 2017.

DesignCon 2025 - 30 Years of Excellence

2 months ago | signalintegrityjournal.com | Patrick Hindle

DesignCon, the premier high-speed communications and system design conference and exposition, celebrated their 30th anniversary with special events such as a 30th anniversary lounge, scavenger hunt, First Timers gathering, Women in Engineering reception and Lunar New Year celebration.
How to Simulate Low Voltage, High Power 2000 Amps to a Dynamic Digital Load

Jan 21, 2025 | signalintegrityjournal.com | Heidi Barnes |Steve Sandler |Benjamin Dannan

Hardware engineers are learning the hard way that power integrity (PI) requires electromagnetic (EM) simulation of the printed circuit board (PCB) power delivery network (PDN). Traditional rules-of-thumb and leveraging data sheet examples are not an option as designs move from hundreds of Amps (A) to thousands. 1000 A across a 100 microhm (µΩ) PCB PDN is still 100 millivolts (mV) of IR drop and 100 Watts (W) of power dissipating as heat.
What Key Characteristics Should You Consider in a Cable Assembly Solution?

Jan 15, 2025 | signalintegrityjournal.com | Maury Microwave

Serving as a signal’s primary pathway between components in RF and microwave systems, cable assembles are critical for ensuring reliable, optimal performance. This article reviews key considerations, such as amplitude stability, phase stability, durability, and flexibility, to help you choose the most suitable cable for your specific objectives.
Created by Engineers, for Engineers: DesignCon Celebrates 30 Years

Jan 14, 2025 | signalintegrityjournal.com | Suzanne Deffree

DesignCon gears up to celebrate its 30th anniversary this January with special events, an expo full of leading suppliers, and its highly regarded educationBetween FedEx, UPS, and Amazon Prime, it’s not unusual to find a package on my doorstep. But it’s rare that I am as delighted as I was when recently opening a package from long-time DesignCon attendee, speaker, and Technical Program Committee (TPC) member Istvan Novak.
The Need for Speed and the Cost in Power

Jan 7, 2025 | signalintegrityjournal.com | Eric Bogatin

Our economy is both fueled and limited by energy sources. Before the Industrial Revolution, human strength and ability were supplemented by animals. We still retain a measure of power in terms of the ability of a horse. One horsepower (hp) is equivalent to about 750 W, which is about 5x what one person can deliver. The Industrial Revolution, which began in 1760, was distinguished by the introduction of energy sources that offered even more power than a horse.
Lifelong Learning: Resources for SIJ Readers

Nov 21, 2024 | signalintegrityjournal.com | Eric Bogatin

If an engineer stops learning, their knowledge can become obsolete in just a few years. This means engineers need to be lifelong learners. Luckily, there are many free resources available to learn new engineering principles, migrate to new fields, and keep up with the latest technology solutions and best design practices.
Understanding Phase Noise Measurements

Nov 14, 2024 | signalintegrityjournal.com | Maury Microwave

The poster, “Understanding Phase Noise Measurements,” provides a clear and concise overview of key phase noise concepts, including its impact on system performance, measurement techniques, cross correlation, confidence factor vs. noise floor, and advanced analysis solutions. Explore phase noise fundamentals using this insightful visual guide from Maury Microwave.
Measuring Battery Impedance

Nov 13, 2024 | signalintegrityjournal.com | Steve Sandler

Recently, Picotest has had several questions from customers working to measure battery impedance. There are numerous publications and articles about testing battery impedance, even from VNA manufacturer’s such as OMICRON Lab, including a useful 2017 application note guide from Florian Hammerle.1This article will discuss some of the reasons for measuring battery impedance.
A JWST Christmas Story

Nov 4, 2024 | signalintegrityjournal.com | Eric Bogatin

While many of us witnessed the Christmas launch of the James Webb Space Telescope as excited public, one engineer in our community saw 20 years of his life being launched into space. His personal story, through his eyes, is now available for the rest of us to experience. John McCloskey, Chief EMC engineer with Goddard Space Flight Center, shown in Figure 1, spent almost half of his career working on the JWST, solving and troubleshooting EMC and RF issues, amongst other test challenges.
Don't Blow Up the Universe

Oct 29, 2024 | signalintegrityjournal.com | Eric Bogatin

I recently received a note from an engineer who asked about a paradox that is often used in prelim exams to trip up EE PhD students. We start with two identical capacitors, one charged to 2 V and the other starting at 0 V. Then we connect them together. This circuit is shown in Figure 1. The first question is, what is the voltage on each after they are connected together? Of course, the voltages become 1 V on each. Now comes the trick question.
