As with all books, this one is the result of the work of many
people. At the top of the list are the many students who have
attended my “High Speed PCB and System Design” classes over
the last ten years. There have been more than 5000 of you.
You have challenged me with your questions, prompted me to
go back and study topics I had long forgotten and pushed me
for better answers. Even more, you have continually asked me
when I was going to write the book that goes with the class.
Without that continual prompting, this book might still be just
a promise. To all of you, thanks for your encouragement and
The next group of people who played a big role in making
this book a reality are all of the senior engineers who taught me
when I was a young engineer. They took their time to explain
difﬁ cult concepts to me; to prepare lectures and classes that I at-
tended at conferences and to write articles and papers that have
been in my reference library throughout my career and from
which I drew upon for this book. As I went through my career,
I vowed that if ever I had the opportunity, I would give back to
my profession as it gave to me and all of the other young en-
gineers that started out with me. More of the senior, seasoned,
experienced engineers need to stay in the industry and share
what they have learned with new engineers. If ever there was
a time when this was needed, it is now because of the rapidly
changing technologies with which we work.
I have worked with hundreds of very good engineers and
designers. From each of them, I have learned things. Many of
them have participated in experiments that were aimed at reﬁ n-
ing the rules I used to do design and to demonstrate concepts.
Many of those experiments are in this book.
Early in my career, I switched from microwave and RF de-
sign to computer design. When this happened, I was privileged
to work with two very good engineers at Amdahl Corporation,
Dan Murphy and John Zasio.
With Dan, I later founded a design company known as
Shared Resources. Dan was a great router developer and we used
his skills to put together a design company and a PCB router
that set the standards for how to route high speed PCBs. Many
of the features in today’s PCB routers came from the work that
Dan did. He made it possible for Shared Resources to design
PCBs that could not be attempted with any of the then available
design tools. Many of the design concepts in this book came
from the work we did designing hundreds of high speed PCBs.
With John, I was able to work on many high-speed designs
and to see how he performed analysis of some fairly complex
problems. He has always had a design and analytical discipline
that stands out among all the engineers I have known and with
whom I have worked. I could always count on him to put to-
gether good analyses and to perform measurements with the
rigor necessary to prove concepts in a conclusive way. He has
been working at engineering since the early sixties and is still
actively working on new and more complex designs. Whenever
I needed a reliable ear to explore an idea, John has been there.
For this book, he did the lab experiments that support the state-
ments about bypass capacitors and he also wrote the section on
that topic. We still ﬁ nd new things to explore.
In the fall of 1989, I was writing design articles for the early
version of Printed Circuit Design magazine. A new editor came
on the scene who did major damage to the articles I submitted.
Some of them were sent back to me with so much red ink, it
looked as though someone had been slain on them. This editor
was Kella Knack who had come from Martin Marrietta where
