Homotopy Methods For Computing DC Operating Points - Trajkovic (Correct)
....operating point is obtained when = 1. This combination of variable stimulus and variable gain homotopies has been named the hybrid homotopy. The modified variable stimulus homotopy, chosen for its simplicity and ease of implementation, has been used in a production version of a circuit simulator [15, 16]: H(x; 1 Gamma )G(x Gamma a) F(x) 12) Choosing a good starting point for the homotopy method is essential to assure fast convergence of the algorithm. In circuit terms, a good starting point may be a solution 9 to a linear circuit or to a nonlinear circuit that has a unique solution. ....
....homotopy embedding (9) has when applied to nodal equations. Modified nodal equations with embeddings that cause presence of nonphysical circuit elements (e.g. occurrence of negative resistors) can sometimes pose numerical difficulties and will have worse performance than the nodal equations [16]. For such equations the embedding of a parameter should be done in a manner that avoids nonphysical network instances. An important issue in using homotopies to find dc operating points is the type of nonlinear functions that characterize nonlinear circuit elements. Most homotopy algorithms ....
