• Various types of I -V curves in two-terminal circuit are obtained by changing bias V,and feedback resistance, 7< . Six states appear in the I -V curves. ON, OFF 1 andFOFF 2-states are statnc. Decaying oscillation appears in I and INN-states and constantamplitude oscillation occurs in II-state. On transition of circuit state, current noiseincrease and decay time elongation of the decaying oscillation are observed, which aresimilar to critical fluctuation and slowing down observed on phase transition ofequilibrium systems. Thus the circuit can be said to undergo some kind of phasetransition. Phase diagram is described in coordinate system of V and 7< . There are twointeresting points, one the presence of' transitiort regions such as metastable andunstable states and the other the presence of singular points such as triple point andcritical point, which resembles van der Waals type liquid-gas transition.
