Abstract

The invention provides a magnetoelectric data trigger triggered by a magnetic field and an implementation method thereof. The magnetoelectric data trigger comprises three layers of magnetoelectric heterojunctions and copper coils uniformly wound on the peripheries of the heterojunctions, and magnetic field pulse trigger signals are provided by electromagnets applied to two ends of the rectangularmagnetoelectric heterojunctions. Magnetization of different degrees is generated by controlling a bias magnetic field to induce a magnetostriction phase through the magnetoelectric effect, so that thedynamic magnetomechanical strain of the magnetoelectric heterojunctions is regulated and controlled, and the output voltage maintaining and converting functions are achieved by changing the directionand residual magnetism occurring in the bias magnetic field under the excitation of an alternating magnetic field. Therefore, the ferroelectric layers of the magnetoelectric heterojunctions generatenonvolatile voltage and cause the change of the output high / low level state, thereby realizing the tracking and maintaining functions of classic data triggering. Compared with a traditional D trigger,the magnetoelectric data trigger has the remarkable advantages of being low in loss, quick in response, simple in wiring and the like, and can replace the traditional D trigger and be applied to a modern digital system.

Description

technical field [0001] The present invention relates to the technical field of D flip-flops, in particular to a magnetoelectric data flip-flop triggered by a magnetic field and a realization method thereof. Background technique [0002] Data flip-flop (D flip-flop) is an information storage device with memory function and bistable state transition. It is used in the design of modern large-scale digital integrated circuits, especially in synchronous sequential integrated circuits, clock frequency division, data latch An important logic unit circuit in a design. D flip-flops are widely used in digital systems and computer systems, and can be used as logic function devices such as digital signal registration, shift registration, frequency division, waveform generation, and counting. [0003] The existing D flip-flop is composed of many gate circuits or many transistor circuits, but the transistors prepared by the existing CMOS technology have leakage current and channel effect...
