Then a universal emulator of mem-elements is implemented with linear Voltage Control Floating Impedance (VCFI) circuit and a current integrator. By the choice (resistor/capacitor/inductor) of different type components, the emulator can simulate the electrical behavior of memristor, memcapacitor, and meminductor, respectively. Finally, the proposed emulator is applied to RLC series resonant circuit, and the circuit influences of mem-elements from both the time domain and frequency domain are studied. PSPICE simulations verify that the correctness and effectiveness of the universal emulator. Key words: Memristor; Memcapacitor; Meminductor; RLC series resonant circuit 1 引言
