基于Knowm忆阻器的新型忆感器模型的设计与分析

Design and analysis of new meminductor model based on Knowm memristor

以往有关忆阻器模型及其应用研究主要集中于忆阻器基本概念构建并分析忆阻器模型及其等效电路模型,而基于市场上商用忆阻器件的研究则很少.本文根据忆感器与忆阻器之间的理论关系,基于全球首款商用忆阻器芯片: Knowm 忆阻器,结合第二代电流传输器和跨导运算放大器,构建了一种新型忆感器模型.通过调节输入信号的频率和幅值以及运算跨导放大器的跨导增益,可有效地在电路中实现忆感器忆感值的连续调节.设计了新型忆感器的 LTspice 电路模型和硬件实验电路,以电路仿真结果和硬件电路实验结果验证了新型忆感器模型的有效性和设计方法的正确性.

In the past,the memristor model and its application research have mainly focused on constructing and analyzing the memristor model and its equivalent circuit model based on the basic concept of memristor,while the research based on commercial memristive devices in the market has been rare.According to the theoretical relationship between meminductor and memristor,a new model of meminductor is constructed based on Knowm memristor,the first commercial memristor chip in the world,combined with the second-generation current conveyor and transconductance operational amplifier.By adjusting the frequency and the amplitude of the input voltage and the transconductance gain of the transconductance operational amplifier,the continuous adjustment of the meminductance can be effectively achieved in the circuit.The LTspice circuit model and hardware experimental circuit of the proposed meminductor are designed.The validity of the new meminductor model and the correctness of the design method are verified by LTspice simulations and circuit experiments.
