Synopsis of Presentation


Common-mode currents are often the dominant source of radiated emissions from an electronic product. Unlike differential-mode currents, conventional circuit analysis programs do not predict common-mode currents, and the mechanisms that excite them are more difficult to visualize and quantify. The generation of common-mode currents by "ground noise" has been widely discussed, but another unexpected source is lack of layout symmetry. This talk will explain, demonstrate, and quantify how asymmetric structures excite common-mode currents.

Biographical Sketch

Thomas Jerse holds a double appointment as an Associate Professor of Electrical Engineering at The Citadel in Charleston, SC, and as an Associate Technical Fellow of The Boeing Company, working as an EMC analyst. He earned a PhD in EMC at the University of Kentucky and has spent over 25 years designing compliant products and solving EMI problems with Hewlett-Packard and Boeing. He has written several comprehensive courses in EMC which he has taught to engineers around the world.
