Abstract :
For circuit designing, it is very important to calculate the DC operating points. It is known that if the circuit contains positive feedback loops such as flip-flop and negative resistance circuits, it may have many DC solutions. It is very difficult to find all of the solutions for these circuits. In this paper, we show a very simple Spice oriented Newton homotopy method which can efficiently find out the multiple DC solutions, and perhaps all of the solutions
