Summary :

In this paper, we describe a method of determining the polarity of input terminals of the operational amplifiers which are represented with the nullator and norator model. A circuit containing nullators and norators can be realized by two types of DC stable circuit, one is the conditionally stable circuit and the other the absolutely one. The former is a circuit that, if the sequence of activating operational amplifiers is settled, is stable and the latter is one that is always stable. The necessary and sufficient condition of the absolutely stable circuit is also shown.
