In this paper, a S-type locally active memristor is constructed based on Chua’s unfolding theorem. The analysis of the power-off plot (POP) shows that the introduced memristor has two stable equilibrium states and exhibits bistable characteristics. The S-type DC plot reveals that the memristor has a locally active region of a negative slope. The equivalent circuit of the memristor working near the operating point of the locally-active region is established, based on small-signal analysis method. Then, an oscillating circuit is constructed based on the memristor. It is found by analysis that this memristive system does have complex dynamical behavior. Finally, an analog circuit is built to verify the theoretical analysis.
