Pavlov’s Dog: A Simple Circuit Implementation using a Volatile Memristor

Özet

Memristors are electronic devices, which are widely used in neuromorphic circuit design, because they exhibit some superior properties such as memory and nonlinear behavior. Previous nonvolatile memristor-based associative learning, which is a type of learning mechanism using circuits, has not taken into account the time interval between neutral stimulus and its effect on the circuit, after a long time-lapse. In this paper, a volatile memristor is used instead of a fully nonvolatile memristor in an effort to provide the sensitivity required for the time interval between applied pulses. Also, compared with previous studies, the response of the volatile memristor-based circuit is sensitive to additional input applied pulses. All simulations presented in this work were successfully carried out.
