A Simple MOS Realization of Current Controlled Memristor Emulator

Memristor based circuits is a promising topic in circuit theory due to the time variant resistance and the storage property which is useful in different applications. Due to the lack of memristor samples, the emulators are very useful to be used instead of memristor samples. Moreover the previous emulators are implemented using commercial off the shelf components. In this paper, a new simple MOS realization to emulate current controlled memristor behavior is proposed. The proposed MOS emulator is implemented using TSMC 0.13 mu m technology with dual supply +/- 1.5V which can be easily integrated with any other integrated circuits. The proposed emulator can be tuned for any desired working frequency either low or high frequencies. The mathematical model of the proposed emulator is derived. Furthermore, the functionality of the proposed emulator is tested in memristor-based Voltage controlled relaxation oscillator.
