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.

"Cost
Effective PCB Design" - John
Howard |

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.
About the Presenter:
John Howard is currently working as a Independent Consultant with
specific expertise in the area of Electromagnetic Compatibility and EMC
management. His background includes work as a Electronics Technician prior
to earning BSEE and MSEE degrees. He has worked as a hardware engineer,

"How to Div Grad
Kink and Curl Electrons Into Generating Unwanted Radiated Emissions" - Franz
Gisin |
| Details:
|
[
TOP ] |
| |
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.

"Electromagnetics
Made Compatible" - W. Scott Bennett |
| Details:
|
[
TOP ] |
| |
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.
About the Presenter:
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. |

"EMC Regulations
and Regulators: What's New, Who's Who" - Barbara Judge |
| Details:
|
[
TOP ] |

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.
About the Presenter:
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,
