Abstract :
The paper deals with a procedure for approximate symbolic analysis of linear circuits in the frequency domain, which is based on a combination of simple parametric approach and topology transformations. The large-change sensitivities are computed using the cofactor matrix which can be obtained by a simple matrix inversion. An effective cofactor-updating strategy based on the use of the Sherman-Morrison formula is also presented.
