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.
