Biographical Notes

George Erdi was born in Budapest, Hungary, in 1939. He received the Bachelor of Engineering degree in 1965 from McGill University, Montreal, Canada and the M.S. degree in 1966 from the University of California, Berkeley. In 1966 he joined the Linear Integrated Circuit Section of Fairchild R&D reporting to M. Rudin., where his activities included the design of the µA722 monolithic D to A converter and the µA725 precision operational amplifier. He co-founded Precision Monolithic Inc. (PMI), located in Santa Clara, in 1969 and Linear Technology Corporation in 1981. At PMI Erdi designed the OP07, which was the first three-stage precision amplifier with internal compensation. The OP07 proved to be so popular that in 1976, Fairchild decided they needed an exact equivalent. The µA714 number was assigned to the project. The designer was Joseph Biran, who had joined Fairchild from Precision Monolithics. It was announced in 1977.
