Jim Williams, who worked for Linear Technology for nearly three decades, started as an applications engineer in the early years of the company. His contributions were many-fold. He was a legendary analog circuit designer, problem solver, writer and mentor to many engineers over the years. Jim passed away in June 2011. Jim taught and did research at Massachusetts Institute of Technology from 1968 to 1979, concentrating exclusively on analog circuit design. Before joining Linear Technology in 1982, Jim worked in National Semiconductor’s Linear Integrated Circuits Group for three years.
In nearly 30 years with Linear, Jim had the unique role of staff scientist. Jim Williams was named Innovator of the Year by EDN magazine in 1992 and elected to the Electronic Design Hall of Fame in 2002. He wrote dozens of articles and application notes and was author/editor of several classic books on analog circuit design.
