Abstract:
This is really a love story. Not about antique technology, but about a wild period of jaw-dropping creativity that was the golden era of the bipolar transistor. The almost magical properties of the BJT and the diverse set of problems it was called on to solve are nothing short of astonishing: a DAC that automatically corrects for transistor sizing, an LDO loop invariant to PVT, a multiplier made from one transistor, and an equation for synthesizing...well, almost anything. No, this is not just nostalgia. It is a lesson in creative thinking. It is a blueprint for the next golden era of circuit magic.

Speaker biography:
Chris Mangelsdorf (S'77 - M'84) received a B.S. in physics, magna cum laude, from Davidson College, Davidson, NC in 1977. In 1980 and 1984, he received the M.S. and Ph.D. degrees in electrical engineering at M.I.T. where he held the first Analog Devices Fellowship. He has been associated with Analog Devices since summer employment in 1980 and has been a Fellow of Analog Devices since 1998. From 1996 to 2013, Dr. Mangelsdorf worked in Tokyo, running the Analog Devices Tokyo Design Center and then adding responsibility for the Shanghai and Beijing Design Centers with the title of Asia Technical Director. In 2013, he moved to the Analog Devices San Diego office, where he was engaged in the development of high-speed A/D converters. As of September 2020, Chris has retired from Analog Devices and is now an independent consultant and author of the "Shop Talk" column in Solid-State Circuits Magazine. Dr. Mangelsdorf is a member of Phi Beta Kappa and Sigma Pi Sigma (physics) and has served on both the ISSCC Program Committee and the AdCom for the IEEE Solid-State Circuits Society. He holds 18 patents and has won the ISSCC Best Evening Session Award 10 times.
