摘　　要：近年来,科研人员为研究忆阻器的电气特性及其在电路中的应用,建立了多种整数阶忆阻器的Verilog-A模型,但分数阶忆阻器的Verilog-A模型还未见报道。文章提出了一种分数阶忆阻器的Verilog-A模型,对其相关特性进行了分析,总结了参数对忆阻器电气特性影响的规律,并将此模型应用于脉冲宽度调制(PWM)电路中,通过改变分数阶阶次来调整PWM电路的占空比。实验结果证明了分数阶忆阻器Verilog-A模型的正确性和实用性。In recent years, researchers have established a quantity of Verilog-A models of integer-order memristor to study the electrical characteristics of memristor and its application in circuits, but the Verilog-A model of fractional-order memristor has not yet been reported. In this paper, a Verilog-A model of fractional-order memristor was proposed, and its related characteristics were analyzed. The law of the influence of parameters on the electrical characteristics of the memristor was summarized. This model was applied to the pulse width modulation(PWM) circuit, and the duty cycle of the PWM circuit was adjusted by changing the fractional order. The experimental results proved the correctness and practicability of the Verilog-A model of fractional-order memristor.
