Generalized modified nodal formation for circuits with nonlinear resistive multiports described by sample data

An analytic derivation to obtain the generalized modified nodal circuit equation which is suitable for nonlinear multiports with discrete data description is represented. For this purpose, a numerical data model for the nonlinear multiport is defined, which has the same form as the ordinary transfer parameters of the network. This approach uses a recently defined two-graph method which can be applied to a circuit containing nonlinear multiports, with the partition of the terminal equations into linear and nonlinear submatrices to facilitate the solution of the circuit equation.<>
