TLELO-CUAUTLE, E.  and  AGUILA-MEZA, J.. Enhancing the symbolic analysis of analog circuits. J. appl. res. technol [online]. 2005, vol.3, n.2, pp.150-160. ISSN 2448-6736.

A new symbolic-method is introduced to enhance the calculation of symbolic expressions of analog circuits. First, the analog circuit is transformed to a nullor equivalent circuit. Second, a new method is introduced to the formulation of a compact system of equations (CSEs). Third, a new method is introduced to the solution of the CSEs, by avoiding multiplications by zero to improve the evaluation of determinants. Finally, two examples are given to show the usefulness of the proposed methods to calculate fully symbolic transfer functions.
