This work introduces a novel data-driven modified nodal analysis (MNA) circuit solver. The solver is capable of handling problems featuring elements for which solely measurement data are available. Rather than utilizing hard-coded phenomenological model representations, the MNA reformulates problem such that solution found by minimizing distance between states fulfill Kirchhoff's laws, to belonging data. In this way, previously inevitable demand representations abolished, thus avoiding introduction related modeling errors and uncertainties. proposed applied linear nonlinear RC-circuits half-wave rectifier.
