SPI Proceedings: Voltage/Current Waves Sensitivity in Hybrid Circuits with Nonuniform MTLs

The paper presents an innovative technique for a sensitivity evaluation in linear hybrid circuits. The circuits can contain elements with both lumped and distributed parameters when generally lossy nonuniform multiconductor transmission lines (MTLs) form their distributed parts. A novelty consists in a possibility to obtain not only voltage and current sensitivities in respective nodes and branches of the circuit, but also the sensitivities of voltage/current waves propagating along the MTLs´ wires. The technique uses the modified nodal analysis (MNA) method in conjunction with MTLs´ chain-admittance matrices conversion to determine the (x,s)-domain solution. Finally the numerical inversion of Laplace transforms is applied to get the required (x,t)-domain results
