Ji. Alonso et Aj. Santana, SIMULATION OF ARBITRARY NONUNIFORM FREQUENCY-DEPENDENT INTERCONNECTIONS USING PSPICE, Electronics Letters, 31(4), 1995, pp. 253-254
Several methods for obtaining equivalent circuits compatible with PSPI
CE for the transient analysis of nonuniform single transmission lines
have been proposed. All of them suffer from inaccuracies and approxima
tion errors. The method proposed in the Letter uses the Analog Behavio
ral Modeling option of PSPICE, avoiding the problems of synthesising e
lectrical circuits. The method allows the analysis of distributed line
ar and nonlinear networks and is easy to use.
