摘　　要：现有的各种固定电阻、可调电阻器(电阻箱)和数控可编程电阻器都有不足之处,不能满足科研等场所对制备时间、灵活性的要求。文章提出在数字电路中加入忆阻器并且通过控制施加电压的时间得到一种可变电阻器的设计模型。在Simulink平台上对基于忆阻器的可变电阻器建模并进行了验证,同时与传统数控可编程电阻器进行了比较。实验数据表明,基于忆阻器的可调电阻器模型在灵活性、阻值连续性、阻值精度等方面与数控可编程电阻器相比都有明显改善。All the existing fixed resistors, adjustable resistors(resistance boxes) and digitally controlled programmable resistors have shortcomings, which can not meet the requirements of time and flexibility in scientific research and other fields. In this paper, a memristor is added to digital circuit, and a design model of variable resistor is obtained by controlling the time of voltage application. Memristor-based variable resistor is modeled and validated on the Simulink platform. The comparison with traditionally controlled resistors is also made. The experimental data show that the memristor-based adjustable resistor model has a significant improvement over the digitally controlled programmable resistors in terms of flexibility, resistance continuity and resistance accuracy.
