摘　　要：二值型忆阻器具有独特的二值特性和非易失特性,使其在存储器、数字逻辑电路、模拟电路等领域中展现出了巨大的应用潜力。但是二值型忆阻器仍然存在生产技术难题,尚未商业化,因此建立二值型忆阻器仿真器并研究其应用具有重要意义。该文基于运算放大器、电流传输器、乘法器、二极管、电阻、电容等基本电路元件设计了一种二值型忆阻器电路仿真器,并通过Pspice仿真和硬件电路验证了该仿真器具有典型的二值特性、非易失特性和阈值特性。将该电路仿真器应用于模拟电路中的比例放大电路中,通过仿真分析和实验验证,采用电压脉冲信号修改忆阻器仿真器的阻值,无需改变电路结构实现增益在线修改。Due to its binary characteristic and non-volatility, binary memristor shows great application potential in the fields of memory, digital logic, and analog circuits. To date, binary memristors still have technical difficulties in production, and thus their emulator design is of significance for exploring their applications. A binary memristor emulator circuit composed of the operational amplifier, current conveyor, multiplier, diodes, resistor and capacitor is proposed. The Pspice simulation and circuit implementation of the emulator have verified the non-volatility, binary characteristic and threshold effect. The circuit simulator is applied to the proportional amplifier circuit of the analog circuit. Through simulation analysis and experimental verification, the resistance value of the memristor simulator is modified by the voltage pulse signal, and the online modification of the gain is realized without changing the circuit connection.
