Compact circuit model and hardware emulation for floating memristor devices

A compact circuit model and physical hardware emulation for floating memristors are presented. By utilizing memristor ?resistance? as a state variable, and constructing a hardware emulator using a low-complexity modular structure, the model-based emulation can replicate diverse behaviors of different device types. Our hardware emulator for a voltage-actuated, threshold sensitive, two-terminal, floating memristor demonstrates experimentally memristor dynamics. The emulator is capable of computing any arithmetic operations without any disturbance associated with composition of modular structures.
