Optimized extraction of alternating current model parameters of bipolar transis-tors includes extraction of junction capacitance model parameters and forward transittime model parameters.The use of Levenberg-Marquardt algorithm to find a modelequation least-squares fit to measured device characteristics is efficient.The modelequation of the junction capacitance can be derived from the depletion layer approxi-mation.The optimized junction capacitance model parameters have been extractedwith the average error of 1% (between calculating curves and measuring curves).Tosimulate forward transit time exactly,the model equation in SPICE2G program hasbeen revised according to the measured results.The better optimized model parametersdescribing forward transit time have been obtained using this revised model equationfit to measuring curves.The average error between calculating curves and measuringcurves is only 1.02%.According to our experiment,the following conclusion can beobtained:It is necessary to restrict the exchange range of the model parameters in or-der to make the value of parameters consistent With the physical meaning and this me-thod can also reduce the measuring errors to a certain extent;The efficiency of fitt-ing to measured curves depends on the model expressions.The precision of the obta-ined model parameters are determined by that of the measured data.
