RMCEMC March Meeting

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 explained demonstrated, and quantified how asymmetric structures excite common-mode currents.
