A continuous-level memristor emulator and its application in a multivibrator circuit

This paper presents a new memristor emulator circuit. The circuit is built around the current-feedback operational-amplifier and exploits the nonlinear transfer characteristic of the operational transconductance amplifier to provide continuous change in the memresistance. This is in contrast with many of the available memristor emulators which can provide only binary memresistance levels. Moreover, the emulator enjoys a low impedance input and is suitable for current driving rather than voltage driving. The functionality of the proposed memristor emulator is confirmed by implementing a well-known reactance-less multivibrator circuit. Experimentally obtained results are included.
