J. appl. res. technol [online]. 2022, vol.20, n.3, pp.347-354.  Epub 17-Feb-2023. ISSN 2448-6736.  https://doi.org/10.22201/icat.24486736e.2022.20.3.932.

This paper proposes a current-controlled grounded memristor emulator circuit based on single four-quadrant analog multiplier, a resistor and a capacitor. The behavioral model of the proposed emulator circuit is analyzed, highlighting its characteristics. Experimental results are given to investigate its ability for different operating frequencies and they are in accordance with theoretical analysis and simulation results. By using a divider circuit, the memristance variation in the time domain is obtained. It is observed that the pinched hysteresis loop at high frequency loses symmetry due in part to the shift that introduces a multiplication of sinusoidal signals.
