有源忆阻器伏安曲线与电路频率之间的关系

忆阻器是具有记忆特性非线性电阻器,是现实的第四种基本二端电路元件。文章以光滑三次型非线型函数描述的有源磁控忆阻器模型为例,利用Multisim计算机仿真软件,进一步研究有源忆阻器伏安曲线与电路频率之间关系,讨论有源忆阻器输入电流的突变特性。结果表明:由光滑三次型非线型函数的有源磁控忆阻器模型构成的电路具有边界效应,电流具有突变特性。

Relationship between Voltage-current Curve and Circuit Frequency of an Active Memristor

With the active magnetic control memristor model described with smooth thrice non- linear function as an example,the relationship between the voltage- current curve and circuit frequency of an active memristor was further studied with Multisim. The saltation characteristic of input current of an active memristor is also discussed.The result shows that there is boundary effect in the circuit constituted with the active magnetic control model described with smooth thrice non- linear function. The current of the circuit has saltation characteristic.
