Nonlinear Circuits Handbook, Edited by Dan Sheingold, Analog Devices, 1976.

This was the first major book devoted exclusively to nonlinear circuits including multipliers, modulators, mixers, logarithmic amplifiers, rms-to-dc converters, and other translinear circuits. Many Analog Devices technologists contributed to the book, including Barrie Gilbert and Lew Counts. The book is still popular as a fundamental reference on the subject.
