Hermann Gummel

From Wikipedia, the free encyclopedia

Hermann K. Gummel is a pioneer in semiconductor industry.

Gummel joined Bell Labs in 1957. Since this time he made a number of fundamental contributions in areas central to electronic design. Among the most important of his contributions are the Gummel–Poon model which made accurate simulation of bipolar transisors possible and which was central to the development of the SPICE program; Gummel's method, used to solve the equations for the detailed behavior of individual bipolar transistors,; and the Gummel plot, used to characterize bipolar transistors. Hermann also created one of the first personal workstations, based on HP minicomputers and Tektronix terminals and used for VLSI design and layout, and MOTIS, the first MOS timing simulator and the basis of "fast SPICE" programs.

Hermann Gummel was the first recipient of Phil Kaufman Award (1996).
