I didn't mean to hide anything from you :) I have mentioned MNA or modified nodal analysis, and in all the links to qucs it shows how to add entries to the matrices involved in the solution of the circuit equations. Here is a direct link to the MNA matrix formulation: http://qucs.sourceforge.net/tech/node14.html > There is also a lot of good work made by the finnish guys (Valimaki et al) > about the usage of the so called "transient suppressors".
