Computing symbolic transfer functions of analog circuits by applying pure nodal analysis

Abstract

A method focused on computing symbolic transfer functions (TFs) of analog circuits is presented. In order to perform a pure nodal analysis (PNA), all non-NA-compatible elements are transformed to be NA-compatible ones using nullors. A reasonable amount of computer effort is saved through applying the nullor properties in order to reduce the order of the matrix Y/sub NA/ by one for each nullor. Throughout the paper, the suitability and appropriateness of the proposed analysis technique, to be used as an analytical tool, is demonstrated.
