Abstract
In this paper, we proposed a fully floating memristor emulator with long-term memory characteristics. The circuit comprises operational amplifiers and an analog switch. Switching between incremental and decremental modes is easily achieved by changing the polarity of the input signal. The key feature of the emulator is its long-term memory, made possible by the switch and voltage follower. The correctness of the derived formula is verified using Matlab, and the emulator's pinched hysteresis loop and non-volatility are assessed using LTspice. Additionally, an experimental platform was constructed for physical testing, with the physical results showing consistency with the simulations. Finally, the proposed emulator was applied to a simple read-write circuit, demonstrating its practical applicability.
期刊介绍：
Integration''s aim is to cover every aspect of the VLSI area, with an emphasis on cross-fertilization between various fields of science, and the design, verification, test and applications of integrated circuits and systems, as well as closely related topics in process and device technologies. Individual issues will feature peer-reviewed tutorials and articles as well as reviews of recent publications. The intended coverage of the journal can be assessed by examining the following (non-exclusive) list of topics:
Specification methods and languages; Analog/Digital Integrated Circuits and Systems; VLSI architectures; Algorithms, methods and tools for modeling, simulation, synthesis and verification of integrated circuits and systems of any complexity; Embedded systems; High-level synthesis for VLSI systems; Logic synthesis and finite automata; Testing, design-for-test and test generation algorithms; Physical design; Formal verification; Algorithms implemented in VLSI systems; Systems engineering; Heterogeneous systems.
