The tree-pair method in comparison with some symbolic analysis techniques

The tree-pair method is a novel approach to symbolic analysis of analog circuits. This paper outlines and illustrates the method while gives some variant description, and then compares it with some known methods in many aspects. The depiction and comparison indicate that tree-pair method is more facile than the others. Combining with some techniques, such as symbolic expression approximation and hierarchical decomposition, it should be feasible for symbolic analysis of practical analog integrated circuits.
