Investigation of transistor networks concerning feedback structures

Gives a computational realization of a theorem of N.O. Nielsen and A.N. Willson, Jr. (1980) for studying the DC operational point of transistor networks in a qualitative manner. Although this theorem is constructive in nature a direct approach leads to tedious combinatorial computations. Based on a backtracking technique an algorithm is proposed which circumvents these difficulties. Some heuristics are explained. By means of some examples the usefulness as well as the limitations of the algorithm are shown.<
