Z,Y,H,G, and S Parameters for Circuits Using Spice

Krishnapuram Kumar

Abstract


Spice compatible circuit files and procedures for linear two port Z,Y,G,H and S parameters are given. Starting from definitions of two port parameters the various parameters are determined for a fictitious circuit. For the same parameter determination one or more than one change in spice netlist statements are indicated. Three different files for the determination of S parameters is given. The thoery behind the written netlist is explained. Different input spice files for Z,Y,G,H parameters using independent voltage sources, resistors, dependent current/voltage sources, independent current sources with spice compatible procedures are given. The Z,Y,G,H parameter output for a typical file are generated and given in the form of tables and graph. Analog behavioral option of pspice is also used for two of the four files to calculate all the four S11,S12,S21 and S22.
