Direct Construction of Circuit Equation Based on Directed Graph with Direct Tree

Nodal analysis ,loop analysis and cutset analysis are three methods with different advantages and disadvantages to analyze linear circuits In the fields of Computer- Aided Circuit Analysis-- CACA, nodal analysis is the only method used to achieve steady response of linear circuit The paper put forward that loop analysis and cutset analysis are not adopted in CACA because common branches are difficult to be determined by logic by computer Then direct tree and directed graph with direct tree are introduced briefly and two criterions are presented so that loop analysis and cutset analysis can be used in CACA Furthermore, the author bring forward loop analysis based on directed graph with direct tree to program in CACA, and an example shows that the method is better than that of nodal analysis
