Abstract :
We investigate an integrated circuit model coupling the modified nodal analysis (MNA) equations and
the non-stationary drift-diffusion equations. By considering perturbations only in the MNA equations we could obtain a first perturbation estimate, which implies well-posedness, for this partial differential algebraic equation (PDAE). It is assumed that the linear circuit without the semiconductor branch is of index 1, that the diode contacts are connected by a capacitive path and that the semiconductor region is one-dimensional.
