Abstract
A simple, single-expression approximation is derived for the Fermi-Dirac (F-D) Integral F1/2(x) in the range -4 = x = +12. This approximation is more accurate (less man 1-percent error throughout) and more useful in device analysis and computer modeling. The approximation procedure is general and can be used to find approximations for F-D Integrals of any order and to any arbitrary degree of accuracy.
