Volume 4 of Encyclopedia of Electronic Circuits contains many new, not previously cov
ered circuits, organized into 104 chapters. Circuit titles are listed at the beginning of
each chapter, for references. Most of these circuits appeared in publications since 1988
and should be very useful for obtaining new ideas for research and development, or sim
ply to fill a need for a specific circuit idea or application. Those wishing to develop their
own circuits will find this book indispensable as a source of ideas, to see how others have
solved a problem or approach a design, and to obtain a starting point toward a new
A brief explanation accompanies almost every entry. Those that have been omitted
are either repetitive, obvious, or too involved to describe in few words. In this case, the
reader should consult the original sources (as listed in the back of the book).
W2 also wish to extend our sincere thanks to Ms. Loretta Gonsalves for her fine
work at the word processor. Her skill and cooperation contributed much to the success
ful completion of this book.
This fourth volume in a series that has sold more than 175,000 copies, includes schematics and descriptions for the latest circuitry used in computers, controls, instrumentation, telecommunications, sensors, and numerous other electronics applications. A companion to previous volumes, this work features more than 1000 all-new curcuits in 100 alphabetically-arranged categories.
