Powering Digital Boards - Distribution and Performance

The Greater Boston Chapter of the IPC Designer's Council will
hold its next meeting on Tuesday, Feb. 9th at 6pm.

Istvan Novak, SI Staff Engineer with Sun Microsystems, will
speak on the relevant issues of today's digital systems with
respect to the often overlooked (or "assumed") power systems.

As system speeds continue to increase, the multiplicity of
voltages and the integrity of the overall power system can
quickly become major obstacles to physical design and system
performance. This presentation will examine:

- Proliferation of supply voltages. Why it happens, do we see
an end to it?
- Power distribution requirements: Historical perspective,
road map. Do we have any roadblocks in front of us?
- Power distribution components: what should we know about caps,
inductors, planes. Why are caps with higher ESR sometimes
better? How do planes help us?
- Things to avoid, and how to avoid:
Resonance among bypass capacitors
Resonance of power planes
Peaking in PLL and EMI filters
- A simple approach for bypassing


Note there is a meeting fee of $5/members; $10/non-members

About the Greater Boston IPC Designer's Council:
(for info on the National group visit http://www.ipc.org )

Since 1995 the local chapter has been bringing the physical
design community face-to-face with many of the stockholders
in the development of electronic products, at all levels. We
attempt to bring fundamental, current, and leading edge prob-
lems, processes and solutions to light. Only by continuous
and studied exposure to these many (and sometimes divergent)
interest groups can today's physical designer mediate and add
value to the product development process.

Non members are welcome at meetings, but expect some pressure
to join...<grin>. Non-members RSVP please, reply/sender-only
