2005-11-07BuchFinding Beneficial DAE Structures in Circuit Simulation Schwarz, Diana Estévez; Feldmann, Uwe; März, Roswitha; Sturtzel, Sandra; Tischendorf, CarenCircuit simulation is a standard task for the computer-aided design of electronic circuits. The transient analysis is well understood and realized in powerful simulation packages for conventional circuits. But further ...

2005-11-03BuchModeling Circuit Systems Coupled with Distributed Semiconductor Equations Tischendorf, CarenFor a refined network analysis, we are interested in circuit simulation including distributed models of semiconductors. We construct a mathematical model for nonlinear electric networks containing semiconductors described ...

2003-12-10BuchNumerical Analysis of DAEs from Coupled Circuit and Semiconductor Simulation Soto, Monica Selva; Tischendorf, CarenIn this work we are interested in the numerical solution of a coupled model of differential algebraic equations (DAEs) and partial differential equations (PDEs). The DAEs describe the behavior of an electrical circuit that ...

2005-11-04BuchNumerically well formulated index-1 DAEs Higueras, Inmaculada; März, Roswitha; Tischendorf, CarenFor index-1 DAEs with properly stated leading term, we characterize dissipative and contractive flows and study how the qualitative properties of the DAE solutions are reflected by numerical approximations. The best situation ...

2005-11-04BuchNumerically well formulated index-2 DAEs Higueras, Inmaculada; März, Roswitha; Tischendorf, CarenFor linear index-2 DAEs with properly stated leading term we characterize contractive and dissipative flows. We study under which conditions the qualitative properties of the DAE solutions are reflected by the numerical ...

2005-11-03BuchPDAE models of integrated circuits and perturbation analysis Bodestedt, Martin; Tischendorf, CarenA model for a linear electric circuit containing semiconductors is presented. The modified nodal analysis leads to a differential algebraic equation (DAE) describing the electric network. The non-linear behaviour of the ...

2005-10-21BuchRecent results in solving index 2 differential-algebraic equations in circuit simulation März, Roswitha; Tischendorf, CarenIn electric circuit simulation the charge oriented modified nodal analysis may lead to highly nonlinear DAEs with low smoothness properties. They may have index 2 but they do not belong to the class of Hessenberg form ...

2005-11-15BuchStructural analysis for electric circuits and consequences for MNA Schwarz, Diana Estévez; Tischendorf, CarenThe development of integrated circuits requires powerful numerical simulation programs. Of course, there is no method that treats all the different kinds of circuits successfully. The numerical simulation tools provide ...

2005-11-03BuchTopological analysis of qualitative features in electrical circuit theory Riaza, Ricardo; Tischendorf, CarenSeveral qualitative properties of equilibria in electrical circuits are analyzed in this paper. Specifically, non-singularity, hyperbolicity, and asymptotic stability are addressed in terms of the circuit topology, which ...
