Stefanović D., Kayal M. Structured Analog CMOS Design

Springer, 2008. — 283 p.This book describes a structured analog design approach that makes it possible to simplify complex analog design problems and develop a global
design strategy that can be used for the design of different analog cells. The basic concept consists in analog cell partitioning into the basic analog
structures and sizing of these basic analog structures in a predefined procedural design sequence. The basic analog structure specifications are derived from circuit-level requirements, and thus its sizing in the environment imposed by the circuit demands less effort. Furthermore, the procedural design sequence ensures the correct propagation of design specifications, the verification of parameter limits and the local optimization loops.
The proposed transistor-level design procedure is based on the continuous MOS modeling approach and relies on the device inversion level as a
fundamental design variable. Since all important design parameters can be expressed as continuous functions of the device inversion level, the design
optimum as well as the technology limits can be easily found.
Finally, the developed design procedure is implemented as a CAD tool that guides and assists the user during analog design tasks and provides an
interactive interface that allows instantaneous visualization of design tradeoffs.
All material is presented in organized and structured way. The transistor-level design is based on the EKV modelling approach which leads to new way of thinking and approaching design problems. The circuit-level design is given in the form of procedural design scenarios. The final chapter provides the examples on the design of complex amplifiers topologies used as a part of Delta-Sigma modulator system. The described design procedure is implemented as a design tool that can be downloaded from the site analog.eplf.ch.
