May 14, 2002: " EMC Regulations and Regulators: What's New, Who's Who" by Barbara Judge

Abstract: Change is the one sure constant there is, and it's certainly true about worldwide EMC regulatory activities. Maxwell was able to describe electromagnetism with just four equations, but it takes thousands of standards to regulate EMC throughout the world, with dozens more being adopted or modified each year. This presentation will cover in survey fashion some of the more pertinent EMC standards that have been recently published for use worldwide, with focus on changes to be expected when (and if) the new version of the EMC Directive is adopted in the EU.

The EMC regulators are also going through changes - certification activities previously the responsibility of governments are also being performed by the private sector, and governments are changing their long-established procedures. What these changes entail and who the players are will be discussed with respect to effort required to obtain EMC compliance for products in today's marketplace.

Bio: Barbara Judge is Vice President of Compliance Certification Services, Chair of the TCB Council, and Vice-Chair of ACIL EMC Committee. She has been working in the EMC regulatory field since 1991, and prior to that she was VP of Sales at Spinnaker Software. She may be reached at 408-463-0885 extension.104 or at: bjudge@ccsemc.com

April 9, 2002: "Electromagnetics Made Compatible" by W. Scott Bennett

Abstract: The existing literature of Electromagnetics has obviously been written almost exclusively for theoreticians and mathematicians, and not for practicing engineers and technicians. And, the time for that to be corrected has long passed. The primary objectives of this presentation are to clarify the basics of Electromagnetics, to show why it causes problems, and to show how a good many of those problems can be eliminated or moderated. Those objectives are met by using a physical point of view, many descriptive figures, and nothing but high-school mathematics. Also, an occasional comparison is made of what is described here and what is given in the literature — to verify what is presented here, and to clarify what is given there. The overall objective is to start to make Electromagnetics more compatible — to study, to learn, and to work with.

Bio: Scott Bennett was a radar repairman in the USAF from 1948 to 1952. He then alternated working as an electronics technician and studying electrical engineering from 1952 to 1967, earning a BS, MS, and PhD in 1963, 1965, and 1967, all in EE, and all from Syracuse University. He was an EE Instructor at Syracuse from 1965 to 1967; an Assistant Prof. at Virginia Polytechnic Institute from 1967 to 1970; a Staff Engineer for Burroughs Corporation in City of Industry, CA from 1970 to 1974; and an MTS for Hewlett-Packard Company in Loveland and Fort Collins, Colorado from 1974 until 1990 when he retired. Since "retiring" his raison d'etre has been to make Electromagnetics much more understandable for all concerned.

March 12, 2002: "How to Div Grad Kink and Curl Electrons Into Generating Unwanted Radiated Emissions" by Franz Gisin

Abstract: Anyone who has spent any length of time wandering around within the EMC discipline, will, on occasion, take time out to pause and reflect on exactly what is it about pushing electrons around on conducting materials that causes them to generate propagating electromagnetic waves in their wake. We already know the size of the structure plays an important role. Structures excited at their natural resonant frequencies radiate at higher levels. We also know different shaped structures, whether they are optimized for maximum radiation — for example an antenna, or optimized for minimum radiation — for example a collection of information technology equipment assembled on a turntable for an EMC emission test, radiate with different efficiencies.

But if we dig a bit deeper, we cannot help but wonder if some portions of the structure radiate more efficiently than others. For example, electromagnetic fields from a simple resonant dipole antenna can be mathematically expressed as a sum of three point sources located at the ends and the middle of the dipole. The implication is that radiation along the dipole elements is not uniform. If this is so, then we must ask ourselves what intrinsic qualities inherent in the shape of a structure causes electrons in some areas of the structure to generate higher levels of electromagnetic radiation than others.

If we can gain a better understanding of the relationships between structure size and shape, electrons in motion, and propagating electromagnetic waves, then we can become better EMC engineers by not designing in these kinds of structures into our products. We know Maxwell's equations accurately describe all electromagnetic phenomena, and so a good starting point is to disassemble these deceptively compact equations and see if we can gain any insight by looking at them in richer detail. We can also gain understanding by modeling and simulating structures that we often encounter in the EMC profession, for example, printed circuit boards and their associated traces, cables, and electronic enclosures. From these two approaches we can then formulate some practical "best design practices" that will help us build products that radiate with minimum efficiency.

Come join us at the March chapter meeting of the IEEE EMC Society and discover for yourself how not to div grad kink and curl electrons into generating undesired electromagnetic fields.

February 12, 2002: "Cost Effective PCB Design" by John Howard

Abstract: The subject of this presentation will be some of the features in multilayer printed circuit boards which seriously contribute to poor Electromagnetic Compatibility and signal integrity. Featured will be some very common routing practices which are not much of a problem for some signals but are very much a problem for others. Finite element analysis will be presented to highlight these issues from very modest MHz to significant GHz. Finite element method tools readily display the solutions to these problem features. Comprehension about the hazards from these common board construction practices will contribute to better quality signals and fewer PC board turns. This is the "engineered" solution to reducing PCB design cost, and schedule impact.

January 8, 2002: "Circuit Design Trends and Challenges in Multi-Gigahertz Microprocessors" by Stefan Rusu

Abstract: Moore's law drives the VLSI technology to smaller transistors and higher clock frequencies. As VLSI process features shrink deep into submicron territory, leading microprocessor designs have broken the 1GHz limit. This creates new challenges for designers at both the chip and the system level. This presentation will review the trends in submicron design and present the challenges ahead.

At the chip level, the metal interconnects are getting slower with every generation. Copper interconnects and low-K dielectrics will only temporarily ease the burden. To make up for this slowdown and still meet the increasing frequency targets, designers employ aggressive design techniques, like domino logic. This provides higher speed, but with a higher power dissipation. Another emerging technique for achieving higher frequencies is to use dual Vt transistors. The power supply voltage levels are dropping with every process generation, while capacitive and inductive coupling are becoming an increasing concern.

At the system level, bus interface speeds are increasing with every generation. The bus design is shifting from a common clock timing mode to a source-synchronous design that offers wider timing margins. Flip-chip packaging provides better power distribution and shorter interconnects.
