A Memristor Emulator Circuit Using CNFET

A carbon nanotube field effect transistor (CNFET) based memristor emulator has been designed and proposed. The proposed memristor emulator circuit utilizes active building block in form of voltage differencing transconductance amplifier (VDTA). The proposed emulator circuit employs two VDTAs, two grounded resistors, one grounded capacitor and one analog multiplier. The working concept along with the detailed derivation of the mathematical model of the circuit has been discussed analytically and numerically to certify the operation of the emulator proposed. The operations of the proposed emulator circuit, as governed by the circuit equations, have been verified by performing simulations in standard CNFET model.
