Main Fast Techniques for Integrated Circuit Design

# Fast Techniques for Integrated Circuit Design

This book is a result of many years in active design work in the semiconductor industry.
I started my career as a theoretical physicist working on dense matter theory and
electromagnetic ﬁelds in an astrophysical environment. After a few years my interest
turned toward integrated circuit design, where there were also electromagnetic ﬁelds,
and I have been working in this ﬁeld ever since. It is a rich environment for the study of
nature and mathematics and I am thrilled to be a part of it. As a theoretical physicist one
always tries to get a handle on experiments and observations by doing simple math-
ematical modeling, and in my stint as a postdoc in the theoretical physics group at
Caltech in the 1990s I was part of an Order of Magnitude Physics, 103c class that took
this idea to town. The students were asked to estimate things such as the amount of
rubber dumped into the air from cars on LA’s freeways and how long a grass straw
would grow in a week with a given precipitation and sunlight. The class was taught by
Professor Peter Goldreich and Professor Sterl Phinney, and it opened my eyes to the
power of estimation. In my career I have always tried to understand things by ﬁrst
estimating the impact of a certain effect and then verifying it. This analysis method has
been a great help for me personally and the people I have been lucky enough to tutor.
I have also encountered many other engineers and academic professionals who are very
good at following these same principles. This book is an attempt to bring this way of
I refer to the analysis method as estimation analysis, but many people use the term hand
calculations, which I ﬁnd to be rather misleading. Simply put, we consider complex
problems in a way that do not require exact full solutions. The book will show that this
approach can be taken for almost any problem, be it circuit analysis, high frequency
phenomena, sampling concepts or jitter, to name a few. The scope of the book is from
simple circuit theory, familiar to most engineers, to high frequency theory with a
particular focus on integrated circuit applications, to systems such as data converters
and phase-locked loops (PLLs). The applications are intentionally fairly broad, to
illustrate the power of the techniques. What is different in this book compared with
other similar ones is a strict physical approach where all situations are modeled
carefully, often from ﬁrst principles, followed by useful solutions and illustrative
relationships after some algebra. Once such a model is established one can use it as a
starting point for simulations where the simulator is used to ﬁne-tune the design.
