Özet

In this paper, we present a memristor emulator based on voltage difference transconductance amplifier (VDTA). The proposed memristor emulator circuit contains only one VDTA as an active element and single grounded capacitor which benefits from the integrated circuit. Furthermore, it can be utilized MOS-capacitance instead of the external capacitor in the circuit. The complete memristor emulator is laid by using Cadence Environment using TSMC 0.18 mu m process parameters. It occupies an area of 35.7 mu m x 29 mu m. Its simulation results are given to demonstrate the performance of the presented memristor emulator in different operating frequencies, process corner, and radical temperature changes. Moreover, prototype circuit is implemented to confirm the theoretical analysis by employing the single LM13700 commercial device as an active element. Experimental results of the designed memristor emulator are given to investigate its ability for different operating frequencies, the capacitance value and resistor value and DC supply voltage. The experimental results are in accordance with theoretical analyses and simulation results.
