Abstract

Isolators for signals and/or powers transmitted between two circuits configured to operate at different voltage domains are provided. The isolators may have working voltages, for example, higher than 500 Vrms, higher than 1000 Vrms, or between 333 Vrms and 1800 Vrms. The isolators may have a fully symmetrical configuration. The isolators may include a primary winding coupled to a driver and a secondary winding coupled to a receiver. The primary and secondary windings may be laterally coupled to and galvanically isolated from each other. The primary and secondary windings may include concentric traces. The primary and secondary windings may be fabricated using a single metallization layer on a substrate.
