A CAD tool suitable for LTI systems analysis

Abstract

A CAD approach permitting us an easy frequency response simulation of LTI systems implemented with analog electronic-devices, is introduced. This technique uses the features of symbolic analysis in order to get more insight into the behavior of the circuit. An important thing is that a reasonable amount of computer effort is saved through modeling several analog circuits using nullors. Most important is that using nullors, a pure nodal-analysis method is established in order to improve the computation of transfer functions. The paper also demonstrates the suitability and appropriateness of the proposed simulation technique to be used in education.
