Generic and Practical Emulators for the Voltage-Controlled Memristor Models

In this chapter, generic and simple emulator circuits for the grounded and floating voltage-controlled memristor models are introduced. As of now, there is no significant work available in the literature on the development of emulator circuits for the voltage-controlled memristor models, which have many potential applications. The new designs of emulator circuits presented here are based on a shaping circuit, a second-generation current conveyor (CCII), and an analog multiplier. The proposed emulator circuits would be compatible with different memristor models, such as the Hewlett Packard (HP) Model, the Generalized Memristor Model (GMM), and the Voltage ThrEshold Adaptive Memristor (VTEAM) with a linear window function. The proposed emulator circuit development technique is flexible because the resulting circuits can be used as a floating emulator to enable series, parallel, and hybrid connections. Here, both series and parallel connectivity of the proposed emulator circuits have been studied experimentally. Qualitative analysis and SPICE simulation results match well with the experimental measurements of the emulator circuits implemented using off-the-shelf discrete components.
