A method for the computation of large tolerance effects
Renato N. Gadenz, M. Rezai-Fakhr, Gábor C. Temes · IEEE Transactions on Circuit Theory · 1973
A method is described for the tolerance analysis of linear circuits with large element variations. It utilizes the adjoint network concept to set up a reduced system of equations, solvable by either Gaussian elimination or iteration. The process appears to be considerably more economical than simple repeated analysis of the circuit, provided that not all circuit elements are toleranced.
