Novel method of sensitivity evaluation in hybrid circuits with nonuniform distributed parts

The paper deals with a new method for a sensitivity analysis in linear hybrid circuits. The circuits in view can contain elements with both lumped and distributed parameters when multiconductor transmission lines (MTL) play the role of their distributed parts. The technique is based on the modified nodal analysis (MNA) method serving to the basic description of the circuit. Firstly the frequency-domain sensitivities formulae are derived then the numerical inversion of Laplace transforms (NILT) is applied to obtain the time-domain sensitivities. In this paper a novel method for evaluation of sensitivities with respect to distributed parameters is elaborated while considering lossy nonuniform multiconductor transmission lines.
