Özet

This work presents a novel resistorless memristor emulator circuit designed in both grounded and floating configurations. The grounded memristor consists of a Current-Controlled Current Conveyor Transconductance Amplifier (CC-CCTA) and a capacitor. On the other hand, a floating memristor includes a CC-CCTA and a capacitor, along with an additional Operational Transconductance Amplifier (OTA). These proposed emulators are electronically controllable owing to the internal structures of active elements. Theoretical analysis and simulation results have been obtained for the proposed designs. Simulation results have been conducted utilizing the LTspice program and TSMC 180 nm technology has been used for internal structures. In these results, the effects of the changing capacitor values, different frequencies, electronic tunability, reactions to temperature change, and pulse response have been investigated. Subsequently, a chaotic Jerk circuit has been implemented incorporating the proposed memristor emulator. The chaotic behavior of the floating memristor has been investigated using the LTspice simulation software.
