A new extraction method for unit bipolar junction transistor capacitance parameters

Abstract

A new method for extracting the area, peripheral and corner capacitance components of bipolar junction transistor, using measurements versus bias on a number of different structures is presented and validated. The same model with different parameters is used for the three components. Validation has been made using a quasi-2D simulator. Finally, it is shown that this method gives accurate results regarding the goodness of fit.
