“…The main task of an electronic filter is to transmit signals desired frequencies and suppress signals at undesired frequencies. The first memristive element used by the researchers in the filter circuits is the memristor (Driscoll et al, 2010;Gursul & Hamamci, 2019).Similarly, the filter circuits with memcapacitors are among the topics in the literature (Arora & Niranjan, 2017;Li et al, 2017). An active low-pass filter circuit with the memcapacitor, which will be discussed in this study, is given in Figure 6, and the full form of this circuit with the memcapacitor emulator is presented in Figure 7.…”

Elektrik yükü ile manyetik akı arasındaki ilişkiyi tanımlayan ve uygulanan gerilime bağlı olarak direnci değişen iki uçlu bir elemanı temsil eden memristör (hafızalı direnç) elemanının keşfi, memristif sistemlerin temelini oluşturmuştur. Kondansatör ve indüktör elemanlarının memristif sistemlerle ilişkilendirilmesi ile memristif sistemlerin çalışma alanı genişletilmiş ve memristöre ek olarak memkapasitör (hafızalı kondansatör) ve memindüktör (hafızalı indüktör) olarak adlandırılan yeni hafızalı devre elemanları literatürde yerini almıştır. Memkapasitörün karakteristik davranışı, elektrik yükü ve voltaj olarak tanımlanan iki durum değişkeninde sıkışmış histeretik döngü şeklinde gösterilmektedir. Bu çalışmada, bir alçak geçiren filtre (AGF) devresinin analizi için memkapasitör elemanı ve onun emülatör devresi ele alınmıştır. Böylece standart kondansatörlü ve memkapasitörlü alçak geçiren filtre devrelerinin performans kalitesi karşılaştırılmıştır. Karşılaştırma sonucunda memkapasitör tabanlı alçak geçiren filtre devresinin klasik filtre devresine göre nispeten daha iyi filtreleme performansı sağladığı sonucuna varılmıştır. Ayrıca memkapasitörün standart kondansatöre göre devreden daha az akım çekmesi sonucunda memkapasitörün tükettiği reaktif gücün standart kondansatörün tükettiği reaktif güçten daha az olduğu gözlemlenmiştir. Bu katkılar, gelecekteki elektronik çalışmalar için umut verici sonuçlar sunmaktadır.

“…The introduction of memristive components into filter design is exemplified in a study of a lowpass filter where the authors replaced a resistor with a memristor and a capacitor with a memcapacitor [20]. A potential reconfigurable FIR filter design with memristive weights was analyzed by Professor Strukov and his research group [21].…”

When the memristor was fabricated for the first time, it launched an entirely new field of research. Many of the published papers regarding memristors are primarily theoretical and are based on computer simulations. Some recent papers analyze the memristor’s programming circuits, but to the best of the authors’ knowledge, no memristor has been embedded into a commercial analog circuit. This paper is practically oriented and it is based on the experimental results obtained by measurements on the circuit prototype. We present a solution for automated programming of a commercially available memristor and its implementation in tunable active bandpass filter design. The novelty of this paper is that the active bandpass filter’s central frequency could be programmed during the filter operation, so a pause for memristor state-switching is not required. The experimental results are promising, and open up possibilities for the memristor’s application in analog systems.

“…The study showed a change from RC LPF to mem-C LPF, and then from RC LPF into mem-memcapacitor LPF, to demonstrate time-variance in the transfer function and cut-off frequency of the resulting filters. 14 Authors in Reference 15 detailed experimentation on an RLC series circuit modified with a memristor and memcapacitor. In demonstrating the signal division (filtering) model, the authors replaced the resistor and capacitor in a typical double-pole, passive, RLC series circuit with a memristor and memcapacitor respectively.…”

This article presents the enhancement of Legendre Optimum low pass filter (LPF) in terms of reusability and bandwidth, based on the programmable memristance of memristors. Two LPFs of the third order, operating in the MF and VHF range, and designed using the insertion loss method are presented.At 600 kHz and 110 MHz, two Knowm memristors working in the forward ion-conduction mode replace R s and R L in the filter circuit. Their conductance and therefore memristance is varied such that R off − R on decreases monotonically and∕R off − R on ∕ > 0. Results show a bandwidth enhancement of up to 540 at 600 kHz, and up to 100 at 110 MHz. A reusable, cost-effective, variable bandwidth filter is achieved from the original fixed bandwidth filter.
