Nine Essential Principles of Signal Integrity

SIJ technical editor Eric Bogatin notes that there are some problems that occur over and over again across product families and applications. They have a handful of essential principles at their underlying root cause. In this blog, he explains that if we really understand these underlying principles, the root cause of the problems will be more apparent and their solutions closer to implement.

Build Your Own Low-Cost Power Rail Probe

Probing signals with a bandwidth below 100 MHz and voltage sensitivity above 100 mV is a no-brainer. Regardless of the type of signal or the source impedance, the venerable 10x passive probe is the answer. However, at bandwidths >100 MHz and with voltage sensitivity <100 mV, the 10x passive probe may not be the best option. In this article, SIJ technical editor Eric Bogatin introduces an easy-to-implement, low-cost alternative to the 10x passive probe specifically for power-rail measurements.

A Simple Demonstration of Where Return Current Flows

This simple measurement demonstrates the most important principle in SI/PI and EMI: that the return current will flow in the path of lowest resistance below about 10 kHz. But above about 10 kHz, the return current will begin to redistribute in the return path to be adjacent to the signal conductor. Read on to learn more.

Seriously Funny Science Worth Watching

The Ig Noble Prizes are awarded every year for an individual or group who “did something that makes people laugh and then think.” In our time of increased stress what a perfect combination of activities for engineers to participate and experience: laughing and thinking.
