resident known for his brilliant mind, eccentric personality and flowing white beard, Pease worked for 33 years as an analog chip designer at
in nearby Santa Clara.
Among his most important designs were a temperature-voltage frequency converter taken on medical research expeditions to Mt. Everest, a seismic pre-amplifier chip to gauge lunar ground tremors on
Apollo missions to the moon and the LM337 negative voltage regulator.
Pease was born Aug. 22, 1940, in
, Conn., and earned a bachelor's degree in electrical engineering at the
He worked for George A. Philbrick Researches in
designing operational amplifiers, analog computing modules and voltage-frequency converters until 1976, when he moved to National Semiconductor. He left the company in 2009.
In addition to well-regarded scientific volumes such as "Troubleshooting Analog Circuits," Pease also wrote
He also was the author of "How to Drive Into Accidents — And How Not to."
