A NOVEL EXTRACTION METHOD FOR BJT-PARAMETERS

Róbert Lórencz - Christian Reckleben - Karsten Hansen

   We report on a reliable parallel parameter extraction method of the Spice Gummel-Poon (GP) model. It is based on a non-linear least-squares fit of the measured base- and collector dc-currents and results in the optimal parameter set. The goodness of the fit, a level of confidence in each parameter, the degree of coupling between parameters and the sensitivity of the model with respect to each parameter are calculated.
