Abstract

In this paper, a systematic and efficient formulation method is presented for obtaining the network functions of linear or linearized time-invariant circuits. The method employs the modified nodal approach to obtain the system equations. The technique is based on developing a matrix formulation for generating network functions. By using both symbolic manipulation of algebraic expressions and numeric processes, the network functions are expressed with a matrix-based method. Application examples are given to illustrate features of the method.

Key words: Network functions, modified nodal approach, formulation method.
