This paper reports a unified asymmetric memristive diode-bridge (UAMD) emulator with the current constraints for each pair of parallel bridge arms, which is implemented by an asymmetric diode-bridge cascaded with a parallel resistor and capacitor (RC) filter. The mathematical model is established and its pinched property is confirmed by multisim circuit analysis, MATLAB numerical simulation and hardware experiment. Besides, the UAMD emulator is expanded to the general cases and four diodes on symmetric bridge arms owning two situations are taken as two expanding examples.

统一的非对称忆阻二极管桥仿真器和硬件确认

本文报告了一个统一的非对称忆阻二极管桥 (UAMD) 仿真器，其中每对并联桥臂都有电流限制，该仿真器由与并联电阻和电容 (RC) 滤波器级联的非对称二极管桥实现。建立了数学模型，并通过multisim电路分析、MATLAB数值仿真和硬件实验验证了其收缩性。此外，将UAMD仿真器扩展到一般情况，并以具有两种情况的对称桥臂上的四个二极管作为两个扩展示例。
