Curve-search algorithm for DC analysis of non-linear electronic circuits

The solution of the original DC analysis problem is reformulated as a search for a certain point in functional space which belongs to the curve in the same space. the generalized matrix equation of the hyperplane normal to this curve is easily derived and a new iterative algorithm is presented. Some critical situations arising in non-linear circuit simulation and the behaviour of the new approach in these cases are considered. Six application examples are given.
