The Third Edition of CMOS Circuit Design, Layout, and Simulation continues to cover the practical design of both analog and digital integrated circuits, offering a vital, contemporary view of a wide range of analog/digital circuit blocks phase-locked-loops, delta-sigma sensing circuits, voltage/current references, op-amps, the design of data converters, and much more. Regardless of one's integrated circuit (IC) design skill level, this book allows readers to experience both the theory behind, and the hands-on implementation of, complementary metal oxide semiconductor (CMOS) IC design via detailed derivations, discussions, and hundreds of design, layout, and simulation examples.
Though it is a very good book I think if one wants specific knowledge of Layout in CMOS he can use Dan Clein's book,Analog layout Alan Hastings,for Modelling tsividis
One of the best books you can find on CMOS layout and design. Although, its approach is sometimes very simple, but the breadth of information and especially the information regarding the process and what really are the issues at that nano-scale level of the transistor, it has been an enlightening experience. This book is really vast in topics but when you are working on CMOS circuit design, gives a sense of completeness and leaves no gaps in between as most of the textbooks do.
Reading this book as part of my Final Year Project. Its quite a helpful book, though the approach is more numeric than theoretical. The book also has a second edition, something to do with Mixed-signal designing I guess.
