This book introduces readers to a variety of tools for automatic analog integrated circuit (IC)
sizing and optimization. The authors provide a historical perspective on the early methods
proposed to tackle automatic analog circuit sizing with emphasis on the methodologies to size
and optimize the circuit and on the methodologies to estimate the circuit's performance. The
discussion also includes robust circuit design and optimization and the most recent advances in
layout-aware analog sizing approaches. The authors describe a methodology for an automatic flow
for analog IC design including details of the inputs and interfaces multi-objective
optimization techniques and the enhancements made in the base implementation by using machine
leaning techniques. The Gradient model is discussed in detail along with the methods to
include layout effects in the circuit sizing. The concepts and algorithms of all the modules
are thoroughly described enabling readers to reproduce the methodologies improve the quality
of their designs or use them as starting point for a new tool. An extensive set of application
examples is included to demonstrate the capabilities and features of the methodologies
described.
