Abstract

TLELO CUAUTLE, Esteban; CARLOS, Sánchez López  and  SANDOVAL IBARRA, Federico. Computing Symbolic Expressions in Analog Circuits Using Nullors. Comp. y Sist. [online]. 2005, vol.9, n.2, pp.119-132. ISSN 1405-5546.

A novel method is introduced to compute symbolic expressions in analog circuits modeled by nullors. The proposed method is based on the formulation of a compact system of equations (CSEs) by manipulation of data-structures, which highly improves traditional symbolic-methods. It is demonstrated that by modeling all active devices using nullors, the CSEs is easily formulated by manipulation of both the nullor and admittance interconnection-relationships. Several examples leads us to conclude on the suitability of the proposed symbolic-method to be incorporated within a symbolic simulator.

Keywords : Symbolic analysis; Modeling and simulation; Circuit theory; Data structures; Nullor.
