چکیده
Abstract This paper deals with computational complexity of approximate symbolic analysis. A method for symbolic approximation that exploits the sparsity of circuit matrix to achieve an acceptable speed for large circuits is proposed. The method is based on gradual simplification of a block-decomposed circuit model in the frequency domain. The simplified model is then analyzed symbolically. The algorithm has been developed with the aim of obtaining maximum computational efficiency.
