Wondering what IBIS Open Forum actually does? Mike LaBonte lifts the curtain and invites you to learn more about IBIS models.

Not an official award, per se, but Eric Bogatin gives his top pick for his favorite demo at the recent EMC event in Washington DC.

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.

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.

Ground is NOT a current return path. Read on to see Todd Hubing’s four rules of effective grounding strategy.

If you want help measuring things, there’s no cheaper way to do it than this!

Read Eric’s suggestions on measured voltage noise and download a free sample of Eric and Larry’s new PDN Design book.

Read on to see how to determine if you should you use a differential pair in your test coupon and pay for a 4-port measurement, or use a single-ended test line and only pay for a 2-port measurement.

In this DDR 101 introductory piece, learn about the fundamentals of a DDR interface and some basics of physical-layer testing.
