Elektronik Olarak Ayarlanabilir Memristör Tabanlı Chua Devresinin Gerçeklenmesi

Öz

Fiziksel olarak memristörün 2008 yılında gerçeklenmesinden sonra, memristörler devre tasarımlarında geniş uygulama alanı bulmuştur. Memristör hafızalı olması, lineer olmayan karakteristik göstermesi ve oldukça yoğun bir yapıya sahip olması gibi üstün özelliklere sahiptir. Bu çalışmada elektronik olarak ayarlanabilen memristor devresi kullanılarak kaotik devre kurulmuştur. Beklendiği gibi devrenin kaotik davranışı başarılı bir şekilde elde edilmiştir. Ayrıca, farklı OTA (İşlemsel geçişiletkenliği kuvvetlendiricisi) kuyruk akımlarına göre devrenin kaotik davranışının değişimi de çalışmanın sonlarına doğru analiz edilmiştir.

Öz

After physical realization of memristor in 2008, memristors are found wide application area in circuit designs. Memristor has superior properties such as to have memory behavior, to show nonlinear characteristics and to have ultra-dense structure. In this study, chaotic circuit is built using electronically controllable memristor circuit. As expected, chaotic behavior of circuit is successfully obtained. Additionally, the change of the chaotic behavior of the circuit according to the different OTA (Operational Transconductance Amplifier) currents is analyzed to the end of the study.
