Electromagnetic Compatibility - Methods, Analysis, Circuits, and Measurement, David Weston, CRC Press, 2017 (3rd edition) While I've reviewed many books on EMC, this one by David A. Weston, is the most complete in coverage yet. The 1157-page book covers not only basic and advanced theory of EMC, but includes product design, commercial and military measurement techniques, and … [Read more...]
ESD Effects of Digital ICs
One issue I see fairly often with unshielded consumer or commercial products is CPU resets during periods of immunity testing, such as during electrostatic discharge (ESD) testing. Untreated, this can lead to field failures and associated customer satisfaction issues. The remedy is usually quite simple and IC manufacturers even mention the solution, but it’s usually buried … [Read more...]

Energy Harvesting is Not Fiction Anymore
“About what we did dream today, are the ideas from tomorrow. The tomorrow ideas are the products from the days after tomorrow.” Our environment is changing and everything is becoming “electronified”. Our glasses, our hand gloves, shirts, shoes etc., can be connected already today with our smartphones and can send commands to the machinery surrounding us. We want this comfort, … [Read more...]
Low Loss Thin-Film Metal Inductors with High Current Capability for Power Supply Circuits
TDK Corporation presents the new TFM160808ALC thin-film inductor for power supply circuits, which features a maximum DC resistance of 62 milliohms that is 30 percent lower than for existing types (e.g. TFM160808ALM, 0.47 µH). The new type, whose compact dimensions are just 1.6 mm x 0.8 mm x 0.8 mm, also offers a high rated current of 2.6 A and an inductance of 0.47 µH. In … [Read more...]
