As the existing memristor emulator is excessively complicated,a simple generalized memristor emulator is pro-posed.The emulator is a first order memristor equivalent circuit,which is merely composed of a diode bridge and a series RL filter. The mathematical model of the input port voltage-current relation of the generalized memristive emulator is established,and the cor-responding characteristic analyses are performed.The results by numerical simulation and circuit experiments indicate that the emula-tor meets the definition of generalized memristor,and can exhibit the fingerprint of pinched hysteresis loop of a memristor.The pro-posed generalized memristor emulator has simple circuit structure and no grounded restriction,which is convenient for circuit imple-mentation and application access.
