The Huntsville Chapter of the IEEE Electromagnetic Compatibility (EMC) Society invites you to attend a IEEE EMC Distinguished Lecturer Meeting on September 18, 2014 featuring a talk given by Professor James Drewniak.  The program will begin at 5:30 pm with Gary Ziadeh of Amplifier Research sponsoring a free catered meal.  Professor Drewniak’s technical presentation will begin at approximately 6:15 pm after some short chapter status updates.


Managing intentional currents and anticipating un-intentional currents for EMI design
The signals and logic levels in analog and digital electronics are based on voltages, and a typical university education in circuits, electronics, and digital design is very on voltage-centric. However, the parasitics that limit the performance of a design in practical applications are most easily understood, characterized, and an equivalent circuit model and topology developed from an understanding of the specific signal current path. Similarly for un-intentional current paths that comprise the EMI coupling path and lead to radiation provide a systematic approach for understanding, diagnosing, and mitigating EMI problems. This presentation will detail a methodical approach for identifying current paths – intentional and un-intentional – and detail a means of developing equivalent circuit models for parasitics in signal paths, as well as EMI coupling path models for un-intended current paths, together with example case studies.

Seating is limited to the first 50 people registered. You must Register on VTools as soon as you can, but no later than 5:00 p.m. CST September 18, 2014. Note: If you are not an IEEE member or do not have your IEEE Membership Number please just leave that portion of the form blank. Also, we really only need your name and email address; unfortunately, IEEE’s Vtools does not allow one to remove unrequired fields.

I hope to see you there!
