Verbal explanations are favored over mathematical formulas, graphs are kept to a minimum, and line drawings are used in this user-friendly book. Clear guidance and advice are provided for those professionals who lay out analog circuits. Matching of resistors and capacitors: Includes causes of mismatch, particularly the hydrogen effect and package shift. MOS Transistors: Covers a brief history of floating gate devices, EPROM and EEPROM. Applications of MOS transistors: Expands information on failure mechanisms, including BVdss/Bvdii, SILC, NBTI/PTBI and GIDL and the difference between electrical and electrothermal SOA. Consideration of failure mechanisms as crucial to layout: Integrates further information into many chapters covering various devices. Standard bipolar, polygate CMOS and analog BiCMOS: Covers all three fundamental processes. A valuable reference for professional layout designers.

I have to be honest and recognize that this book is really trying, with a lot of success, to bring the "science" of circuit design closer to the "Art of Integrated Circuit layout". This is the first book that is coming from processing, physics and design toward a better layout practice. Starting from device physics, semiconductor fabrication, examples of various processes, etc., Alan Hastings is concentrating all his energy to make us, the IC Layout Designers, better prepared to understand all the analog requirements. He is explaining in very deep details why we have to obey design rules, why we need matching devices, diodes, and is teaching us how to work with sensitive devices like Resistors and Capacitors in an analog high speed environment. This book represents a MUST for any IC Layout Designer involved in high speed design, small gate size, special exotic processes, etc., anywhere were the understanding of the process is a basic requirement. BiCMOS, Bipolar and CMOS process fabrication issues are explained to the level that becomes directly useful in a day to day practice of an Analog Layout Designer. I would recommend this book for layout people involved in DIGITAL design, so they can get a grasp of what are the issues in analog and try to address them in their world. As gate size shrinks some of today analog solutions start to be needed for tomorrow-digital designs. Signal integrity, low power libraries, cross talk, clocks symmetry, noise in high-speed designs, special guard rings, etc., are already some of the topics that 10 years ago were only the subject of analog designer.
Thank you Alan, I learned a lot from your book and I am happy that you spent the time and effort to make us better prepared for "The Art of Analog Layout".

Even though the author attempts to "dumb" the concepts down to make it more useful for general reference, he uses terms that are not common to most layout designers. Case in point: the term "chirality" is used to describe the symmetry of a given layout. Why not use the term "symmetry" which most people are very familiar with?
If you're a pro at analog layout, don't bother buying this book expecting to learn something new. Chances are, you know most of what is contained in the book. I wish I would've spent my [money] elsewhere. These views are also shared by my peers who have looked over the book and are well-versed in mixed-signal CMOS layout.
