Lee Hill will discuss bias effects and introduces new frequency domain SPICE models.   The discussion will also include how to utilize overlooked characteristics of ferrites for improved printed circuit board EMI suppression.  Lee will discuss the specific types of PCB components, the three types of losses, device biases created by PCB applications, impedance vs. freq. & effects of DC bias and impedance vs. SMT package size vs. bias.


The Presentation will run about 60 minutes.

Biographical Sketch – Lee Hill


Lee Hill is Founding Partner of Silent, an independent consulting firm that specializes in EMC and RF design, troubleshooting and training services to commercial and industrial manufacturers with global distribution in the consumer, computer, network and telecommunications, industrial, medical, scientific and automotive industries. Previously Lee was Principal EMC and Systems Engineer at Digital Equipment Corporation’s Workstation Systems Engineering Group in Palo Alto, California. Lee received the Master of Science Degree in Electrical Engineering & Electromagnetics from the University of Missouri-Rolla, and the Bachelor of Science Degree in Electrical Engineering from the Rochester Institute of Technology.


Lee has twenty years of experience in the EMC design and retrofit of complex electronic systems. He has been teaching short courses on EMC design and troubleshooting for over ten years. Lee consults and teaches worldwide, and has presented classes in Taiwan, Singapore, Mexico, Norway, Canada, South Korea, and the United States. He is also a regular EMC course instructor for Oxford University (England), University of California-Berkeley Extension, General Motors University, and Freescale Technology. In previous years Lee was also an instructor for Agilent Technologies. He has completed a three-year term on the Editorial Review Board of Printed Circuit Design Magazine. Lee holds a US patent for EMI control in portable electronics.


Lee is presently a member of the IEEE EMC Society's Board of Directors (2005-2007), Past Chairman of the IEEE EMC Society’s Distinguished Lecturer Program, and a member of Technical Committee TC-10 on Signal Integrity. He served as Co-Technical Chair of the 2003 IEEE Symposium on EMC in Boston, Massachusetts. He is a past Vice-Chair of the Central New England Chapter of the IEEE EMC Society. In the past four years he has been a frequent featured speaker at IEEE EMC Society fundraising events in cities throughout the US including Seattle, Portland, Chicago, Milwaukee, and Detroit. He has also provided technical presentations to Society chapters in Los Angeles, San Diego, Central New England, Dallas/Fort Worth, Austin, Colorado, and Orange County, California. In 1999 Lee received a Certificate of Appreciation from the EMC Society for significant contributions to education through his annual participation in the Demonstrations and Experiments portion of annual IEEE EMC Symposia. Lee was a member of the original IEEE P1180 ad-hoc committee on low frequency magnetic field measurement for video display terminals.
