Mathematical Formulation

The capacitors are stamped as admittances \(j \omega C\). The inductor is stamped as a branch from port 0 to port 2, with one auxiliary current \(I\) and \(V_0 - V_2 - j \omega L I = 0\), so the model is exact at L = 0 and at DC (ADR-0007). S-parameters come from the stamp through pmrf.rf.mna2s().

(experimental) Modified Nodal Analysis (MNA) stamp.

Can be overridden in sub-classes.

Otherwise converts from another domain (y2mna, z2mna, etc.). Y is preferred because it gives the sparsest stamp; other domains add auxiliary variables.
