Abstract
In this paper, a new memristor emulator circuit is proposed. It is realized by operational transconductance amplifiers (OTAs) and second generation current conveyors (CCIIs). A mathematical model to describe the behavior of presented circuit is derived. Memristance value of the emulator circuit is adjustable by means of a simple change of transconductance parameter (gm) of operational transconductance amplifier in the emulator circuit, amplitude and frequency value of applied voltage across terminals of memristor emulator. Frequency dependent pinched hysteresis loop in the current versus voltage plane holds up to 5 kHz. The breadboard experiment of proposed emulator circuit is built by using CA3080 and AD844 ICs for transconductance amplifier and second generation current conveyor respectively. The results of SPICE simulation and experimental test are given to verify the theoretical analyses. The presented emulator circuit can be used in real world memristor circuit applications such as chaotic systems, programmable analog circuits.
