Bruce Archambeault, Ph. D. IBM Research Triangle Park, NC [email protected] Introduction The use of decoupling capacitors connected between the power and ground planes on a printed circuit board (PCB) is a common practice to help ensure proper functionality and to reduce EMI emissions from printed circuit boards. The proper number of decoupling capacitors, and … [Read more...]
EMI Filters for Cardiac Pacemakers and Implantable Defibrillators
The use of ceramic feed-through capacitors, as well as specific filter designs and installation techniques, can make cardiac pacemakers immune to EMI ROBERT A. STEVENSON, Maxwell Technologies Carson City, Nevada, USA Under the coordination of Wireless Technology Research, L.L.C. (WTR), the interaction between cellular phones and cardiac pacemakers has been widely … [Read more...]
Understanding the Measurement Uncertainties of the Bicon/Log Hybrid Antenna
Surge damage as a result of long cables connected to low voltage data systems can be prevented RICHARD MEININGER & ROBERT BLOUCH Since their first introduction in 1994 at the Roma International Symposium on EMC, bicon/log hybrid antennas have become very popular in EMC labs worldwide. Because there are no band breaks in frequency sweep, test time and effort are reduced. … [Read more...]
