Measuring Sub-milliOhm PDN Impedance

Measuring sub-milliOhms is difficult.  Getting low noise, sub-milliOhm measurements in very small circuits is a bit more difficult.  We recently had the opportunity to support R&D Altanova in performing this difficult measurement, here are some of the results.

Real Time FFT Makes EMI Debug So Much Easier.

Traditional swept-tuned EMI spectrum analyzers and step-tuned EMI receivers may produce misleading or entirely false measurement results when the signal under study is not steady state, but transient. See Eric Bogatin's review of a demo by Lee Hill on this subject.

IEEE EMC SI/PI 2017 Summary

The 60th IEEE EMC SI/PI Symposium took place August 7-11 at National Harbor in Washington DC with the “plan to inspire, envision, and innovate.” The keynote set the stage for this plan as Julius Knapp, FCC Chief of the Office of Engineering and Technology, discussed the status of the FCC and industry EMC standards, the equipment authorization program and enforcement as the wireless space becomes more and more crowded with emerging technologies such as IoT, connected/autonomous vehicles, UAVs, increased satellite broadband and 5G taking off.

The Role of PCB Materials in Printed-Circuit Impedance

Printed circuits for high-speed and high-frequency applications rely on fine-featured transmission lines for signal transmission. Ideally, the loss through these transmission lines is minimal, and this requires an electrical impedance that is consistent and without interruptions, and with a value most appropriate for the types of signals to be transferred through the circuit. However, a number of factors can affect the impedance of a PCB, including the physical and electrical characteristics of the circuit and circuit material, but by reviewing and better understanding these variables, their effects can be minimized.
