“…The advantage of this giant magnetoresistive linear isolator over the previous complex hybrid packaged opto-isolators lies in the simplicity of adding several layers of film and insulation. Low-cost isolation input by simply adding a few layers of film and insulator deposition steps to the standard IC process [9]. Immediately after, NVE Corporation was the first to introduce a monolithic GMR isolator in 1998, which used a coil to generate a magnetic field to realize isolation coupling, but was only applied to the field of digital signal isolation [10] .…”

During the entire electronic system data transmission process, sensors can be used to capture information, and more importantly, isolators can be used to ensure the integrity of data transmission. For a long time, optocoupler isolators have been used to achieve electrical isolation. With the progress of sensing technology and the rapid development of the semiconductor industry, using giant magnetoresistance isolation technology to achieve electrical isolation is more conducive to chip integration. This article first introduces the giant magnetoresistance effect, the explanation of its theoretical model, and the areas that still need to be studied. Then, the principle and working process of the giant magnetoresistance isolator are discussed with its structure as the core. Finally, the development direction of giant magnetoresistance isolation devices is prospected.

This project combines research from the areas of wireless communications, very-large-scale integrated (VLSI) circuit design, virtual environments, and human factors in a coordinated interdisciplinary program. This paper gives a brief description of the overall project. Education in the hardware and software of virtual reality (VR) systems will serve as a testbed for training engineers in this co-design philosophy. Part of this project is the creation of three new classes that cover software engineering for real-time software, design of virtual environments, and design of practical wireless devices. The research part of the project will utilize the C6, a threedimensional, full-immersion, synthetic environment in the Virtual Reality Applications Center (VRAC) at Iowa State to create a new generation of wireless communications devices. This is the first academic program that trains computer engineers and scientists to understand and evaluate the effects of particular hardware and software implementations on human operators. I.
