Inverse ABCD Parameter Determination Using Spice

Krishnapuram Kumar

Abstract


Spice/Pspice Models using the inverse transmission parameters for linear two port analysis are given. The inverse transmission parameter determination for a circuit using SPICE2/Pspice is carried out. While the first procedure and files are for the calculation of Inverse ABCD parameters where the circuit is purely resistive and dependent sources, the second is for general two port network using linear elements and small signal models of active devices like BJT, FETs and high frequency active devices. In the second method, the frequency description FREQ of analog behavioral modeling options of Pspice are used. The obtained model has been tested for a linear active circuit and found to give error free results. The models would be useful in the simulation of cascaded circuits.
