An analog circuit analysis method by node elimination

Sneak circuit analysis method is moving to intelligent and automation direction, the method based on network flow simulation has some representation. With the expansion of the circuit system topology and the increasement of the component's amount, the analysis time increases and the efficiency is difficult to be guaranteed. To solve this situation, the circuit system can be divided into some blocks for analysis. Based on the network flow simulation model, the adjacency matrix of circuit system is established. The analysis matrix of circuit system is obtained by the simplification of the adjacency matrix; use the analysis matrix as the network model for circuit system partition analysis. Select appropriate point from the network cutting point as the partition point, the circuit system can be divided into some sub-blocks by removing these points. Circuit system stratified analysis principle is proposed; determine the division method and analysis objectives of each convention level. This method can correctly analysis sneak circuit problem for circuit system, effectively reduce the analysis time and improve the analysis efficiency. It can be taken as an effective complement of sneak circuit analysis method based on network flow simulation for engineering application.

Electrical Theory

The analysis of circuits is frequently required in the electricity of physics. When analyzing circuits, the general idea is to study the issues related to nonlinear resistance circuits based on commonly used physical and electrical theory. Generally, circuits can be divided into linear resistance circuits and nonlinear resistance circuits. However, for some nonlinear resistance circuit, a small part of them are decomposed through subsection linearity while most of them are adopted the form of hieroglyph combination for subsection decomposition fitting analysis. For the following contents, the author will adopt curve layout method to analyze nonlinear resistance element and relation characteristics of voltage and current; to state the characteristics and nature of common electronic elements in our life, and concepts of concave resistance and convex resistance; to analyze the characteristics of nonlinear resistance circuits through electrical circuit analysis method based on the electrical theorem of physics; finally, to analyze referring to actual cases,study the veracity, verify the feasibility and scientificity of the adopted analytical approach, apply image graphics of the resistance circuits in the convenient way to solve complicated design problems among actual electrical problems.
