A how-to guide to piezoelectric accelerometers
Tim McClune, president of Linear Integrated Systems Inc., discusses the background to a book on piezoelectric accelerometers with integrated electronics with its Russian author, Felix Levinzon.

"It’s actually a good book for designers, to know the designs of our sensors, piezoelectric with internal electronics," Levinzon said. "At the same time I included in the book some measurement results of MOSFETs and JFETs which are used in these sensors. Included also are two parts from [Linear Integrated Systems]. These JFETs have unique parameters, very nice parameters."

Levinzon often uses these small-signal, discrete semiconductors in die form to optimize his accelerometers for small size and performance in extreme temperatures. "JFETs and MOSFETs for analog applications with time have gotten better and better, in regard to noise and other parameters," he said. "But unfortunately there are just a few manufacturers of these devices."

Tim McCune is president of Linear Integrated Systems Inc. (Fremont, Calif.), a developer and manufacturer of small-signal, discrete semiconductors. McClune was a defense and wire service journalist in Washington during the 1980s and 1990s. He enjoys talking with analog enthusiasts, writing about the elegant world of non-digital electronics.
