A new large-change sensitivity invariant for linear networks and new relations between sensitivities
M. Bukowski, A. Filipkowski · IEEE Transactions on Circuits and Systems · 1980
A new large-change sensitivity invariant has been introduced, namely, in the case of a multiport the determinant of a difference of matrices for two values of a single variable element is equal to zero. On the same basis two theorems are proved, showing proportionality of the large- and small-change sensitivities of matrix parameters, as well as of currents and voltages with respect to changes in any single network element. The results obtained can be easily applied to tolerance analysis and design of integrated circult.
