摘　　要：根据分数阶记忆元件之间的转换关系,设计了一种分数阶记忆元件通用等效电路。该等效电路在不改变电路拓扑结构的情况下,通过选择五个阻抗元件的类型,可以将任意一种接地型分数阶记忆元件转换为任意一种浮地型分数阶记忆元件。在仿真实验中,根据提出的通用等效电路,分别实现了三种分数阶记忆元件。对三种分数阶记忆元件的特性进行了分析,验证了该等效电路的正确性。According to the conversion relationship between fractional-order memory elements, a general equivalent circuit of fractional-order memory elements was designed. Without changing the topological structure of circuit, the equivalent circuit could convert any grounding fractional-order memory element into any floating fractional-order memory element by selecting the types of five impedance elements. In the simulation experiment, three kinds of fractional-order memory elements were realized respectively according to the proposed general equivalent circuit, and the characteristics of three kinds of fractional-order memory element were analyzed. The correctness of the equivalent circuit was verified.
