“…In the circuit, the exponential amplifier is used to provide the nonlinearity required for memristive behavior [22]. Another emulator circuit proposed by Alharbi et al has voltage controlled feature and consists of AD844 operational amplifier and analog multiplier elements [23]. In addition to these emulator circuits mentioned, there are also many different emulator circuits in the literature (for more details, see [11] and [24]).…”

Memristor, also known as memory resistor, is considered as the fourth passive electronic element expressing the relationship between magnetic flux and electric charge. One of the most important features of the memristor is that it has low power consumption. Minimizing power consumption is an important issue in the electronic circuits. However, the fact that the memristor element was not yet fully manufactured has led researchers to design memristor-like emulator circuits. These circuits, which approximate the memristor properties, are realized by combining the other existing electronic elements. In this paper, a basic NAND logic gate is considered and the change in power consumption when using a memristor instead of the standard resistor in the gate circuit is examined. For this purpose, the NAND logic circuit was constituted for four different memristor emulators, and the power consumption values of these circuits were obtained by simulation and experiments. These values are compared with the power consumption values of NAND circuits obtained by using standard resistors equivalent to the memristor resistance. The results clearly show that the memristor gate circuits reduce power consumption compared to standard resistive gate circuits.

ÖzBu çalışmada ilk olarak Alharbi, Muthuswamy ile Mutlu ve arkadaşları tarafından literatürde önerilen memristör taklit devrelerinin Multisim programında düşük frekanslarda (5Hz-150Hz) benzetimi yapıldı. Taklit devreleri için farklı frekanslarda akım-gerilim (I-V) eğrileri incelenerek en kararlı çıkış eğrisini veren Mutlu ve arkadaşları tarafından önerilen devre gerçekleştirildi. Bu devre kullanılarak 2. dereceden aktif yüksek geçiren filtre devresi tasarlandı. Memristörlü ve direnç kullanılarak gerçekleştirilen filtre devreleri kalite faktörleri, Bode diyagramları ve kesim frekansları açısından karşılaştırıldı. Memristörlü filtre devresinin 0-10 Hz frekans aralığında direnç kullanılarak gerçekleştirilen filtre devresinden daha iyi süzme işlemi yaptığı görüldü.

In this work, a new flux controlled memristor circuit is presented. It provides a tool to emulate the pinched hysteresis loop. When driven the memristor by a bipolar periodic signal, the memristor exhibits a "pinched hysteresis loop" in the voltage-current plane and starting from some critical frequency, the hysteresis lobe area decreases monotonically as the excitation frequency increases, the pinched hysteresis loop shrinks to a single-valued function when the frequency tends to infinity. The design model numerically simulated and the physical implementation is achieved by using a field programmable analog array (FPAA). The circuit can be modeled and implemented with a changeable nonlinear function blocks and fixed main system blocks. The simplicity of the specific design method makes this proposed model be a very engaging option for the design of the memristor.
