This paper presents a novel carbon nanotube field effect transistor (CNFET) based memristor emulator circuit. The proposed memristor emulator circuit utilizes voltage differencing transconductance amplifier (VDTA) as an active building block. The emulator circuit employs two VDTAs, two grounded resistors, one grounded capacitor and one four-quadrant analog multiplier. The working concept along with the detailed derivation of the mathematical model of the circuit has been discussed analytically and numerically to confirm the operation of the circuit. The operation of the proposed emulator circuit, as governed by the established equations, has been verified by performing simulations using 32-nm Stanford CNFET model. Further, the robustness of the emulator circuit has been investigated by subjecting it to process and temperature variations. Variability analyses reveals significant tolerance towards aforementioned fluctuations in parameters.
