Abstract
AC current sensors are described having a primary current path that is integrated in a substrate or separate from the substrate; one or more conductive loops integrated in the substrate and configured for inductive coupling with the primary current path; and an integrated circuit connected to the conductive loop(s) and configured to measure AC current in the primary current path. The one or more integrated coils or loops can include one or more twisted loops configured to provide differential sensing of current in the primary current path and reject stray magnetic fields. In some embodiments, the one or more integrated coils or loops include one or more pairs of integrated coils or loops, with one coil or loop of each pair on each side of the main current path.
