Abstract

New analytical expressions for the dynamic resistance,transconductance,base-collector internal capacitance,and base-emitter internal capacitance are derived.And a new scheme,to extract the current source parameters,thermal parameter,and small signal parameters at multiple bias points on the normal active region,is developed.The proposed parameter extraction method is robust and very fast.Based on these equations, we propose a new scheme to find out the optimal solution by searching for a full-unknown parameter space.The search space corresponds to 1.17x10 8 points on the error surface, and it takes 12.6 hours to get an optimal model parameters using a 2GHz-desktop PC.This scheme is helpful for the modeling of HBT excluding the local minimum problem in the gradient optimization method and the inaccuracies in the direct extraction methods
