Discover a fresh approach to efficient and insight-driven analog integrated circuit design in nanoscale-CMOS with this hands-on guide. Expert authors present a sizing methodology that employs SPICE-generated lookup tables, enabling close agreement between hand analysis and simulation. This enables the exploration of analog circuit tradeoffs using the gm/ID ratio as a central variable in script-based design flows, and eliminates time-consuming iterations in a circuit simulator. Supported by downloadable MATLAB code, and including over forty detailed worked examples, this book will provide professional analog circuit designers, researchers, and graduate students with the theoretical know-how and practical tools needed to acquire a systematic and re-use oriented design style for analog integrated circuits in modern CMOS.

Mainstream textbooks explain how electronic circuits work, but cover very little on how to conceive them. That is the aim of this monograph, namely to show readers how they can determine currents, channel lengths and widths of CMOS circuits, so as to optimally satisfy design specifications of electronic circuits. The idea underlying the methodology described in this monograph consists in the use of a set of Lookup Tables embodying device data extracted from systematic runs done using an advanced circuit simulator, the same as used for final design verifications. In this way, all parameters put to use during the sizing procedure incorporate not only the bearings of bias conditions and geometry, but also every second-order effect present in the simulator’s model, in particular short-channel effects. Consequently, the number of verification simulations one has to perform is not only substantially reduced, but the designer may concentrate on actual design strategies without being bothered by inconsistencies caused by poor models or inappropriate parameters. This monograph will be of use to engineers and researchers who work on the design of electronic circuits and systems.
