Several trigger circuit designs based on memristors
[Objective]With the continuous advancement of integrated circuits,urgent issues,such as data loss and increased circuit complexity owing to power failures in traditional triggers,demand immediate solutions.Memristors are recognized as the fourth fundamental circuit element characterizing the relationship between magnetic flux and charge and have demonstrated renewed potential for practical applications after continuous development and updates.Memristor-triggered circuits offer an effective way to address issues inherent in traditional triggers while merging storage and computation functionalities within circuits.[Methods]Working on the existing issues from the perspective of integrated circuit design and application,this paper extensively discusses four trigger circuit designs based on the mean metastable switch memristor model(Knowm),specifically SR,D,T,and JK triggers.By fully leveraging the unique characteristics of memristors,such as resistance state transformation,rapid switching,low power consumption,nano-scale size,and compatibility with existing complementary metal oxide semiconductor(CMOS)technology,we propose design approaches for these triggers.These designs aim to effectively address the problem of data loss after power failure in traditional triggers and significantly reduce both complexity and power consumption,thereby propelling progress and innovation in integrated circuits.[Results]Initially,this paper provides an in-depth introduction and analysis of the theoretical foundation of memristors,elaborating on conductance and memristance principles.Subsequently,it outlines the modeling and simulation processes for the Knowm using LTSPICE software,validating its feasibility in circuit designs.Following that,the paper designs SR,D,T,and JK triggers based on Knowm memristors,showcasing design concepts and implementation methods aligned with actual circuit logic and functionalities.Ultimately,through simulations,it evaluates the performance and timing of these memristor-based trigger circuits,confirming their potential in practical applications.[Conclusions]Through comprehensive simulation verification and analysis of experimental results,the paper demonstrates that these memristor-based trigger circuits not only replicate the functions of traditional triggers but also offer significant advantages in circuit complexity,power consumption,integration,and stability.Their non-volatile characteristics ensure data remains intact even in the event of power failure,thereby providing a more flexible and reliable solution for circuit design.The memristor-based trigger circuit designs proposed in this paper open new avenues for tackling traditional trigger issues.By fully leveraging the excellent properties of memristors,trigger circuit properties and metrics can be effectively improved,expanding their potential applications and driving innovation and development in integrated circuits.Looking ahead,memristor-based trigger circuitry is poised to become an important research area in integrated circuits,providing broader development space for integrated circuit design and application.
