Emerging memristor technology is as of late drawing broad consideration due to its potential for several applications. But, the non-availability of solid-state memristive devices puts a practical limitation. So, this paper proposed the concept and design of a practical memristor emulator, which can be used to imitate the behaviour of the well-known ideal memristor model developed by the HP Lab. This circuit contains off-the-shelf components such as AD844, AD633, voltage variable resistor (VVR) and few passive components. This circuit provides voltage tunability, an additional advantage over current tunability, which requires a complex circuitry. All the fingerprints of nano-scale memristor behavior are validated by the derived mathematical relations and simulation verification. Further, the robustness of the circuit has been demonstrated for statistical (10% deviation in passive components) and environmental variations (10% deviation in supply voltages). Also, the proposed circuit has been tested for a wide temperature range. Eventually, the proposed circuit is compared with the previously published emulators to illustrate the advantages of the proposed design.
