Abstract :
This paper presents a method focused on assessing the uniqueness of the DC solution of transistor networks. It determines the conditions for such a network in order to possess multiple DC operating points. The method is based on identifying positive feedback structures (PFSs) by resorting to the definitions given by Hasler (Fosseprez et al, IEEE Trans. Circuits and Sys. vol. 18, no. 3, pp. 393-402, 1989; Hasler, Int. J. Circuit Theory and Appl., vol. 14, pp. 237-262, 1986; Fosseprez and Hasler, ibid., vol. 18, no. 6, pp. 625-638, 1990). The topological conditions for the existence of PFSs at ator and norator level are established.
