Symbolic Nodal Analysis of Analog Circuits Using Nullors
Symbolic analysisSymbolic analysis has been for some years a topic of interest in electronics, because it represents a way to have a better understanding on circuit’s behavior. Through this time, different approaches have been developed to derive expressions that allow representing the circuit’s behavior and then using them to improve circuit’s performance. The Modified Nodal Analysis technique has been adopted as the formulation technique by almost all circuit analyzers. However, when the circuit is modeled by using nullor equivalents, it results in a pure Nodal AnalysisNodal analysis (NA) formulation, because all non-NA-compatible elements are transformed to be NA-compatible ones. The main advantage of using nullor equivalents and more recently mirror-pathological equivalents is reflected in a reduction of the matrix rank, as shown in this chapter.
