Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention will be further described:

[0010] The invention is composed of an operational amplifier, a current follower, a multiplier, a resistor and a capacitor. The model of the operational amplifier is TL084, the model of the current transmitter is AD844, and the model of the multiplier is AD633. A and B in the figure are the two ends of the memristor circuit simulator, v is the voltage at both ends of the memristor, and i is the current flowing through the memristor. The operational amplifier U1 and operational amplifier U2 in part ① constitute a voltage follower with isolation function, and the operational amplifier U3 and four resistors R in part ② sb1 , R sb2 , R sb3 , R sb4 form a differential circuit where R sb1 = R sb2 = R sb3 = R sb4 , then the output signal of the differential circuit is:

[0011] v sub =v A -v B = v (1)

[0012] At this time, the output voltage of the differential circu...

Abstract

The invention discloses a binary memristor circuit emulator, which adopts a binary memristor circuit emulator consisting of an operational amplifier, a current transmitter, a multiplier, a resistor and a capacitor, and adapts to different working frequency ranges by selecting integral circuit parameters. A reverse hysteresis circuit is adopted, so that the two resistance states of the memristor can be kept and switched, and the ratio of the high resistance state to the low resistance state can be changed by adjusting the parameters of the reverse addition circuit. The circuit simulator can bedirectly connected with an actual circuit component, and is suitable for research and application of the memristor in the field of digital logic.

Description

technical field [0001] The invention relates to a memristor circuit emulator, in particular to a binary memristor circuit emulator, which is suitable for the research field of memristors and memristor application circuits. Background technique [0002] According to the mathematical relationship between missing magnetic flux and charge, Professor Cai Shaotang speculated that there is a fourth basic circuit element, the memristor. It is a non-linear two-terminal circuit element, which can be applied in the fields of non-volatile memory, digital logic, neural network and analog circuit design. The high and low resistance states of memristors can be regarded as "0" and "1" of digital logic, and it shows attractive application prospects in the fields of digital logic circuits and non-volatile memories by virtue of its unique binary characteristics. In 2008, the HP lab gave the first physical realization of a memristor using nanostructured passive components. At present, there a...
