Abstract
The present disclosure discloses a magnetic isolator, including a substrate, a magnetic field generating unit, a magnetic field sensing unit, a shielding layer, and an isolation dielectric, where the magnetic field generating unit includes a current conductor, the current conductor is arranged to extend along a first direction on one side of the substrate, the magnetic field sensing unit and the current conductor are arranged on the same side of the substrate, the magnetic field sensing unit is located on a lateral side of the current conductor, and a distance between the current conductor and the magnetic field sensing unit is greater than 0 along a second direction, where the first direction is perpendicular to the second direction; an isolation dielectric is arranged between the current conductor and the magnetic field sensing unit; and an isolation dielectric is arranged within the distance between the current conductor and the magnetic field sensing unit along the second direction, thereby playing a role in electrical isolation, facilitating improving the isolation strength, and simplifying the process. The shielding layer can absorb external interfering magnetic fields, and further improve the signal-to-noise ratio.
