One of the device models used for bipolar junction transistors (BJTs) in circuit simulators like SPICE is the Gummel-Poon model. Gummel-Poon model is an extension of Ebers-Moll model and includes second order effects. Gummel-Poon model defines 19 direct current (dc) and 21 alternating current (ac) parameters for BJT. In this context, all the Gummel-Poon model DC parameters are extracted for the BJT for a particular process. An optimized analysis is proposed for the extraction of the parameters modeling the base resistance of the BJT.
