Our November meeting was .. Signal Integrity Design versus
Radiated Emission Control

Service, 5541 Central Avenue Boulder, CO 80301-2846
What we saw: While it is true
that good signal integrity design can help reduce EMI, it alone is not
sufficient to achieve good radiated emission control. This presentation
discussed where designing for one can help the other and where one
may have more stringent or even conflicting requirements with the other.
In today's competitive markets, it is important for signal integrity
engineers and EMC engineers to understand each other's need to reduce
design iterations and minimize product costs. For engineers responsible
for both disciplines, an in-depth understanding of the similarities and
differences between the two is even more important. In this
presentation, key signal integrity and EMC concepts were reviewed.
Design considerations in the two disciplines were compared and
contrasted at the chip and PCB levels.
Speaker Bio:
Dr. Cheung-Wei Lam is currently a Senior EMC Engineer at Apple Computer,
where he has implemented an EMC design and analysis process to
facilitate on-time compliance at lower cost. At Apple, he is also
engaged in IC, PCB and system level EMC R&D. Prior to joining Apple, he
was a Co-Founder and Principal Engineer of Transcendent Design
Technology. In addition to Transcendent, he has worked in Viewlogic's
Advanced Development Group (formerly Quad Design Technology). During his
years in the EDA industry, he has played key roles in the design and
development of EMC, signal integrity and ground bounce analysis software
tools. From 1988 to 1993, he was with the MIT Research Laboratory of
Electronics, where his focus was on modeling of high-speed interconnects
and superconducting transmission lines. PICTURES FROM THE NOVEMBER MEETING
