Patrick Carrier - Mentor Graphics, a Siemens BusinessAntennas come in all shapes in sizes. In addition to wireless communications, they are becoming ubiquitous in the automotive space as well. Similarly, very high speed digital circuits are pervading these realms. It is the unintentional creation of antennas in these high speed digital circuits that cause Electromagnetic … [Read more...]
Cable Discharge Event (CDE)
AbstractWorst-case Cable Discharge Events (CDE) are poorly understood by most of the product developers as the definition of what is about to happen when you plug in a cable into an appliance’s socket. It is NOT the electro-static charge which could be expected on the cable: outer/inner shield(s) + internal wires, while the cable is fully floating prior to the cable … [Read more...]

Review of MIL-STD-461 General Requirements
IntroductionRecently I noted that my series on MIL-STD-461 test methods was closing since I had accomplished a review on each of the test methods. It seems appropriate to continue with a review of General Requirements – those things common to the various test methods.These requirements have been around since the first release of MIL-STD-461 and MIL-STD-462 dealing with … [Read more...]

What is the Most Important EMC Design Guideline?
INTRODUCTIONEMC design guidelines have always been a popular subject in the EMC design community. What is the most important EMC design guideline, i.e. the guideline with the highest impact on the emission and immunity of electronic circuitry? Studying books and literature from renowned EMC experts often tells us that the most important EMC design guideline is: … [Read more...]
Be Careful with Low Cost/Quality Common Mode Chokes ….
Dear readers, I have been really busy working in training and EMI troubleshooting in the past months. I am happy to be here again with a new post.This month we will see a topic from a real-world situation - very interesting - for electronic designers working in conducted emissions problems.In one of the projects I was involved with several weeks ago, a product was … [Read more...]
Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]
