摘要: The author addresses the problem of estimating inverse node-conductance matrix R a resistive network as in MOS LSI. main result is definition two bounding matrices. Since derivation these matrices depends solely on Tellegen's theorem, therefore applicable to all networks that obey Kirchoff's laws, whether are linear or nonlinear, time-invariant time-varying, reciprocal nonreciprocal. It observed upper bound tends be closer if tree-like. Likewise, lower consists mainly parallel connections identical resistors. From matrices, bounds delays can obtained. >
