Research And Application Of XOR Gate Based On Memristor

With the rapid development of computer technology,logic circuits play an important role in many fields.In integrated circuits,especially Moore's Law is about to fail,in order to effectively continue Moore's Law,electronic circuits impose higher requirements on the performance of these circuits.The emergence of memristors provides an opportunity to solve these problems.In 1971,American Professor CHUA first proposed the concept of memristor.Hewlett-Packard laboratory scientists in 2008 developed memristor physical objects,which confirmed the physical presence of memristors.Memristor is a new type of non-linear nano-scale components,and resistors,capacitors and inductors are known as the four basic passive components.It has been widely used in basic circuit design,integrated circuit design,non-volatile memory design,and biological synapse in terms of nan-scale,non-linearity,low power consumption and non-volatile characteristics.In this paper,the development of memristor is briefly introduced.Hewlett-Packard laboratory model and working principle of memristor are introduced.The research status of relevant characteristics and related literatures is analyzed.It is pointed out that the existing literature uses memristor in logic circuit.To the problems and do the following work on these issues:A XOR gate based on memristor is proposed.The use of memristors alone can not realize an XOR gate temporarily,and the structure of the memristor and the CMOS process are highly compatible.At the same time,the characteristic of the CMOS inverter plays a special role in the logic circuit.Therefore,a hybrid CMOS memristor logic gate circuit scheme is proposed.The logic gate circuit of the hybrid CMOS memristor does not require timing operation,and has a great advantage in terms of the continuation of Moore's Law,the computing speed of the computer,the density of the integrated circuit,and the power consumption of the circuit.In circuits,the role of the CMOS inverter is not just to flip the signal,but also to select the signal.After relevant theoretical analysis and SPICE simulation results,it verifies that the logic function of the designed circuit is completely accorded with the result of XOR operation.Due to the use of memristors and CMOS inverters,these devices are likely to fail.Therefore,the fault analysis of the designed XOR gate circuit is performed in this paper.Multipliers have important applications in real-time image and signal processing,so this paper presents a two-bit binary Vedic multiplier based on memristor.Based on the Urdhva Tiryakbhyam algorithm and combined with the characteristics of binary number operation,the two-bit binary Vedic multiplier is realized by combining all logic gate circuits on the basis of the designed XOR gate circuit.The designed multiplier is verified by theoretical analysis and experimental simulation to verify the correctness and feasibility of this method.After calculation of relevant data,the multiplier has a certain reduction in area and power consumption compared with the comparison multiplier.
