Barrie Gilbert
June 5, 1937 - Jan. 30, 2020
Barrie Gilbert of Beaverton died Jan. 30, 2020 at St. Vincent Hospital from a traumatic brain injury following a fall at home.
Barrie was born June 5, 1937, to Fredrick Arthur and Edith (Tansley) Gilbert in Bournemouth, Dorset, England. His father died in a bombing attack when Barrie was three years old. By age 9, he had started experimenting with electronic circuits. Oscilloscopes had a special fascination to him. At 17 he had his first job in electronics and later studied physics at Bournemouth College. While working at Mullard in 1959 he saw a Tektronix oscilloscope for the first time. He was inspired to design his own oscilloscope which led him to a job at Tektronix in Oregon. He became a very creative circuit designer. In December 1968 he astonished the electronics community with two groundbreaking articles in one issue of the prestigious IEEE Journal. The subject of the two articles became known as the Translinear Principle.
He moved back to England to care for his aging mother for seven years until her death. While in England Barrie worked with Analog Devices of Norwood, Mass. When he returned to the United States in 1977 he rejoined Tektronix out of his love for Oregon as much as for Tektronix. Analog Devices found him so valuable that it was willing to create a laboratory for Barrie in Oregon where his creativity exploded contributing to Analog Device's rapid growth. Since then Analog Devices NW Labs has grown to 21 employees and Barrie Gilbert has become one of the most famous analog circuit designers in the world.
Barrie met his future wife, Alicia Moore, at an electronics conference in 1988 and they were married May 6, 1990.
Barrie's prolific career earned him the Fall 2007 cover and two thirds of the prestigious IEEE Solid State Circuits News. He has been granted 109 U.S. Patents, numerous accolades and awards including an honorary PhD from Oregon State University.
Barrie rearranged sonatas for orchestra or wind ensemble on his synthesizers, wrote poetry and had a collection of museum-class electronics.
Barrie is survived by his wife of 30 years, Alicia; former wife, Myrna; four children, David (Wanda) of Gaston, Timothy of Bend, Lynn (David) of Augusta, Mont., Anne (David) of Eugene; three grandchildren; one great-grandchild; nieces and nephews.
He was predeceased by his parents; two sisters; and one brother.
There will be memorial service at 1 p.m., Saturday, Feb. 29, 2020, at Cedar Mill Bible Church, 12208 N.W. Cornell Road, Portland, OR 97229.

My condolences to Barrie's family. Barrie was a very bright, innovative and inspirational person. He has made many major contributions during his lifetime, a great accomplishment.
I am only directly familiar with a few. The innovation of the idea of IC-based knob-readout, and the subsequent development - with the help of many other Tek contributors -to a production realization, as an integral part of the 7000 series, stands out for me. A brilliant piece of work.
We lost a great innovator and a great guy, but his contributions will last for ever.

It might be impolite to say that I never knew Barrie but, I knew of his work (The Gilbert cell springs to mind) so, thanks for all the brilliant work over the years and RIP.

I am so sorry for Barrie Gilbert... I have often got into discussions with him in ResearchGate forum, as well as in personal email correspondence. He gave me valuable advice. He was an incredible man... a genius. I am so upset...

An amazing man who will be sadly missed by all who knew and loved him.

The world will be a lot quieter without BG

Barrie Gilbert's work touches all our lives through a wide range of electronics products. Barrie was driven by curiosity and is one of the great innovators in the history of electronics. He was a force of nature who could not tolerate accepting less than what he saw as possible. I had the opportunity to work with him for an all-too-brief time. Barrie, you may be gone but your impacts on the electronics industry will endure.

I knew Barrie at Tek and worked with the stroke-writing knob readout board in the 7503. Brilliant, kind, and an "Out of the box" thinker. He evolved as fast as the industry, an unusual accomplishment. He will be missed by many.
Included is a photo of part of the analog vector generator that he used as a proof-of-concept for the character generator for the on-screen readout for the Tektronix 7000-series oscilloscopes.

I am giving my sincere condolences in sadness and wish Alicia and the family the strength to get through this. We never know when it is our time to go or when others need step onto plate and take over. It has been an honor knowing Barrie and receiving a personal tour through his museum and collection of electronics through history. Thank you Barrie
