Abstract
A circuit is provided, comprising a transformer having a first coil that is arranged on a substrate and a second coil that is arranged on the substrate above the first coil, and a dielectric between the first coil and the second coil. The circuit furthermore comprises a guard ring around the transformer. The circuit furthermore comprises a diagnostic circuit () that is configured so as to ground the guard ring in a normal operating mode and to measure a measurement voltage or a measurement current at a measurement impedance between the guard ring and the ground potential in a diagnostic operating mode.
