Barrie Gilbert

Barrie Gilbert (b. 5 June 1937 in Bournemouth, England – d. 30 January 2020 in Beaverton, OR) (→ WikiData) was an analog design engineer well known for his invention of numerous analog circuit concepts, including the Gilbert Cell, and the discovery of the Translinear Principle.

Barrie Gilbert

During the 1950s he pursued an interest in solid-state devices while at Mullard, working on the development of early transistors, and later, the first-generation planar ICs. After some pioneering development of sampling oscillography he emigrated to the United States in 1964 to pursue this interest at Tektronix, Beaverton, Oregon, where he developed the first electronic readout system and other advances in instrumentation.

He returned to England in 1970, where he was Group Leader at Plessey Research Laboratories, managing a team developing a holographic memory, OCR systems and integrated circuits (ICs) for communications applications. From 1972-1977 he consulted for Analog Devices Inc., Beaverton, OR, designing several ICs embodying novel nonlinear concepts.

He returned to the USA and Tektronix in 1977 to pursue HF ICs and process development. In 1979, Analog Devices allowed Gilbert to create the first remote design center for the Company, in Oregon, to persuade him to rejoin the company as their first Fellow.
