Abstract

A grounded memristor emulator consisting of two MOSFETs and a high-frequency first-order RC filter is presented. The suggested memristor emulator reacts to an applied input signal, which is passive and consumes negligible dynamic and static power. Mathematical research confirms the suggested memristor emulator’s existence and that it is incremental. The 45 nm GPDK technology of CVST (Cadence Virtuoso Spectre Tool) was used to test the emulator circuit. The advantages of the proposed memristor emulator are that it has a layout area of 1.7316 μm2 and can function at up to 50 GHz. The primary contribution is the experimental validation of the suggested configuration with ALD1117 a dual P-channel enhancement MOSFET array, an ALD1116 dual N-channel enhancement MOSFET array, and a resistor–capacitor (R–C) tank circuit, which acts as discrete components. However, the performance characteristics of the proposed memristor circuit are tested, and their applications are wave shaping and generation circuits such as Schmitt trigger and Chua’s circuit, respectively. In addition, as a novelty of the modified Chua’s circuit, it is tuned with the different values of the memristor. Comparing this emulator circuit to other memristor emulators on the market, it has a lower power consumption, high operating frequency, and a simpler design.
