Memristor-Based Amplifiers with Non-Inverting and Inverting Gains

Öz

Memristors, which are nonlinear circuit elements, have a big potential to design analog circuits that can not be made using linear time-invariant circuit elements. In literature, some analog circuit applications such as memristor based filter and amplifier circuits have already been examined. Opamp based amplifiers has either negative or positive gains. Memristor-based inverting and non-inverting amplifiers have also been inspected in literature. In this study, for the first time in literature, it is shown how to make a new memristor-based amplifier which can give not only positive but also negative gains.

Memristör Tabanlı Negatif-Pozitif Kazanç Devresi

Öz

Memristörler doğrusal devre elemanları kullanılarak yapılamayacak bazı analog uygulamalar için büyük bir potansiyel vaat eden non-lineer devre elemanlarıdır. Literatürde şu anda memristör tabanlı filtreler ve yükselteçler gibi analog uygulama çalışmaları mevcuttur. Opamplar yükselteç olarak en yaygın kullanılan tümleşik devre elemanlarıdır. Opamp tabanlı yükselteçlerden pozitif kazanca sahip olanlar evirmeyen ve bunlardan negatif kazanca sahip olanlar eviren yükselteçler olarak isimlendirilmektedirler. Eviren ve evirmeyen memristor tabanlı yükselteçler üzerine de literatürde bazı çalışmalar yapılmıştır. Bu çalışmada, literatürde bir ilk olarak, hem negatif hem de pozitif kazanç verebilen, opamplı ve memristor tabanlı bir devre incelenmiştir.
