An optoelectronic-based memristor emulator circuit with a rational memristance function

Abstract

Memristor which has been claimed as the fourth fundamental circuit element in 1971 is a nonlinear circuit element having memory. Recently, an optoelectronics-based memristor emulator is reported in the literature. To the best of our knowledge, a memristor emulator with a rational memristance function has not been reported in literature yet. In this study, a memristor emulator which operates on optic principles or with optic circuit components with a rational memristance function is designed. The optoelectronic-based memristor emulator has two LEDs and an LDR. The emulator is made of off-the-shelf components and easy to build. Using simulations and experiments, it has been shown that the emulator is able to mimic memristor behavior well upto kilohertz region. © 2021, National Institute of Optoelectronics.
