The analysis and prediction of nonlinear behavior in electronic circuits
has long been a topic of concern for analog circuit designers. The
recent explosion of interest in portable electronics such as cellular
telephones, cordless telephones and other applications has served to
reinforce the importance of these issues. The need now often arises to
predict and optimize the distortion performance of diverse electronic
circuit configurations operating in the gigahertz frequency range, where
nonlinear reactive effects often dominate. However, there have
historically been few sources available from which design engineers
could obtain information on analysis tech- niques suitable for tackling
these important problems. I am sure that the analog circuit design
community will thus welcome this work by Dr. Wambacq and Professor
Sansen as a major contribution to the analog circuit design literature
in the area of distortion analysis of electronic circuits. I am
personally looking forward to hav- ing a copy readily available for
reference when designing integrated circuits for communication systems.
