Lauritzen, Peter O.

Biographical Notes

Peter O. Lauritzen was born in Valparaiso, Indiana, on February 14, 1935. He received a B.S.E.E. degree from the California Institute of Technology (1956), and an M.S.E.E. (1958) and Ph.D. degrees (1961) from Stanford University. From 1961 to 1965 he was a Member of the Technical Staff working on semiconductor device research and development at Fairchild Semiconductor R&D in Palo Alto, California. He joined the faculty of the University of Washington in 1965. His research areas from 1965 to 1978 included semiconductor device noise, radiation effects, and device operation at cryogenic temperatures. During the period 1983-1998, he taught courses on analog electronics and devices and conducted research on compact model design. He continued to work part-time on compact modeling of power semiconductor devices from 2000 to 2007.
