Abstract: As a new type of circuit elements, the special memory characteristics of memory elements have attracted extensive attention of researchers. Based on the constitutive equation of memory elements, the conversion relationship between memory elementsis deduced, and the conversion between three kinds of fractional-order memory elements is simulated. The simulation results verify the correctness of the conversion relationship between fractional-order memory elements. At the same time, the influence of fractional order on memory elements is analyzed in detail.
