Memristor emulators with symmetric and asymmetric threshold voltages

2nd International Symposium on Multidisciplinary Studies and Innovative Technologies (ISMSIT) -- OCT 19-21, 2018 -- Kizilcahamam, TURKEYMemristor, a fundamental circuit element, was predicted to exist in 1971 by Leon Chua. Chua used an emulator to show how a real memristor would behave in 1971. A memristive system which behaves as a memristor for some part of its operation has been found in 2008. Unfortunately, not many research institutions or companies have a memristors available in their hands. That's why new types of memristor emulators have been done in literature for research and education purposes. Some memristors or memristive systems are reported to have a considerable threshold value. In this study, different memristor emulators with either symmetric or asymmetric threshold voltages have been made. Diodes are used to obtain these threshold voltages. Its analysis and experimental results are given. IEEE Turkey Sect, Karabuk Univ, Kutahya Dumlupinar Uni
