Tweet [People] People Dawn Hightower | ED Online ID #21059 | April 2009 Gilbert Elected To US National Academy Of Engineering BARRIE GILBERT, a Technology Fellow with Analog Devices, Inc., has been elected to the US National Academy of Engineering (NAE). Gilbert, who directs engineering at the Northwest Labs in Beaverton, OR, is being honored by the NAE for his contributions to the field of analog circuit design. The Gilbert cell, a versatile analog function block, has served as the foundational design for the circuits used in today’s communications systems. Since its invention in 1967, what is known as the ‘Gilbert mixer’ has become ubiquitous in radio transmitters and receivers. A related circuit, known as the Gilbert multiplier, revolutionized the implementation of this mathematical analog function and became the first paper in the Journal of Solid-State Circuits to be cited 100 times. Also notable is Gilbert’s pioneering work on three radically different types of variable-gain amplifiers—the H-AMP, X-AMP, and Z-AMP, which are now used to enable ultrasound image capture —in other medical imaging applications as well as RF power measurement and control. He opened new business lines based on novel IC concepts—particularly the integrated logarithmic amplifiers and RMS-to-DC converters. Recently, Gilbert pioneered new forms of translinear logarithmic amplifiers for use in optical instrumentation in fiber-based communications systems. Gilbert will be inducted into the NAE during the academy’s annual meeting on October 5 in Irvine, CA. IW, Inc.—JOHN MORELLI has been
