This is an excellent book that provides a fresh look at CMOS Analog Circuit Design. Behzad Razavi has a clear writing style that takes the reader from an intuitive level of understanding circuit performance to a mathematical explantion based on this understanding. This text also covers most areas of modern Analog CMOS design including all variations of modern op amps, switched capacitor circuits, feedback, noise analysis, frequency response, stability and compensation, as well as oscillators and PLLs. The material is covered in context of modern sub-micron processes and includes coverage of short-channel effects in these technologies. I have found answers in this book to many of the questions I have come across recently. In particular, Dr. Razavi uses the examples in the book to characterize various circuit performance metrics for typical circuit configurations using a symbolic approach. This results in an expression that highlights which circuit/device parameters contribute to the particular performance metric under study.
