Biography
Leonard Forbes was born in Grande Prairie, Alberta, Canada, in 1940 and graduated from the University of Alberta, Edmonton, with distinction in engineering physics and graduated from the University of Illinois, Urbana, with a Ph.D. in electrical engineering in 1970. He has previously taught at the University of California at Davis, University of Arkansas Fayetteville, Portland State University, and was an IBM Visiting Professor at Howard University, Washington D.C., and Visiting Professor at the University of California San Diego in La Jolla, CA. He was previously an ONR Research Fellow, Distinguished Level, at the Navy microelectronics lab in San Diego for five summers. He is currently a Professor at Oregon State University and an Adjunct Research Fellow of the Micron Advanced Research Institute, Boise, Idaho.
Forbes conducts research on noise in electron devices and circuits at Oregon State. His 1995 publication (L. Forbes, "ON THE THEORY OF 1/f NOISE OF SEMI-INSULATING MATERIALS," IEEE Trans. on Electron Devices, Vol. 42, No. 10, pp. 1866-1869, (Oct. 1995)) describes the l/f noise of semi-insulating materials and is analogous to the Nyquist formula for the white thermal noise or Johnson noise of conductors. More recently a description of Hooge's 30-year old empirical equation has been given by temperature fluctuations and Hooge's parameter is shown to be simply related to the ratio of the total number of conduction electrons and the total number of atoms in the sample. Forbes is on the program committee and an invited speaker at the 1st International Symposium on Fluctuation and Noise in Santa Fe NM, June 2003.
