A Novel Flux-Controlled Memristive Emulator for Analog Applications

Abstract

Emerging memristor technology is drawing widespread attention during the recent time due to its potential diverse applications in nanoelectronic memories, logic and neuromorphic computer architectures. Due to the absence of a practical memristive device, most of the research works in this area are still based on memristor emulator circuits that can be of current-controlled or voltage-controlled type. In this chapter, we introduce two emulator circuits for flux-controlled memductor and memristor. These emulator circuits have been built based on second generation current conveyer (CCII+), one multiplier and a square circuit to mimic the hysteresis behavior of the memristor. The proposed memristor emulator circuits can not only emulate memristive and plasticity function but also can be configured for floating configurations characteristic. Furthermore, we present the mathematical modeling, SPICE simulation and experimental results of the proposed emulator circuits. The series and parallel connectivity of these emulator circuits have been also studied, In addition to frequency analysis of their behavior.
