  • Patent number: 11798741
    Abstract: Micro-isolators exhibiting enhanced isolation breakdown voltage are described. The micro-isolators may include an electrically floating ring surrounding one of the isolator elements of the micro-isolator. The isolator elements may be capacitor plates or coils. The electrically floating ring surrounding one of the isolator elements may reduce the electric field at the outer edge of the isolator element, thereby enhancing the isolation breakdown voltage.
    Type: Grant
    Filed: September 14, 2022
    Date of Patent: October 24, 2023
    Assignee: Analog Devices International Unlimited Company

  • Patent number: 11728090
    Abstract: Micro-scale devices, such as transformers and capacitors, having a floating conductive layer are disclosed. A floating conductive layer may be disposed in an insulator layer and can reduce a maximum electric field between a first planar conductor and a second planar conductor of a micro-scale passive device. Reduction of a maximum electric field between a first planar conductor and a second planar conductor can reduce undesirable effects on electrical components.

  • Publication number: 20220392684
    Abstract: A micro-isolator is described. The micro-isolator may include a first isolator element, a second isolator element, and a first dielectric material separating the first isolator element from the second isolator element. A second dielectric material may completely or partly encapsulate the second isolator element, or may be present at outer corners of the second isolator element. The second dielectric material may have a larger bandgap than the first dielectric material, and its configuration may reduce electrostatic charge injection into the first dielectric material. The micro-isolator may be formed using microfabrication techniques.

  • Patent number: 11044022
    Abstract: Isolators having a back-to-back configuration for providing electrical isolation between two circuits are described, in which multiple isolators formed on a single, monolithic substrate are connected in series to achieve a higher amount of electrical isolation for a single substrate than for isolators formed on separate substrates connected in series. Discrete dielectric regions positioned between isolator components forming an isolator provide electrical isolation between the isolator components as well as between the isolators formed on the substrate. The back-to-back isolator may provide one or more communication channels for transfer of information and/or power between different circuits.
