Abstract: A first inductive structure includes a data coil to transfer data by inductive coupling with a second inductive structure. First and second portions of the data coil are connected to one another at a center tap to conduct respective first and second common mode currents, induced by a common mode transient between: a first ground line coupled to the center tap; and a galvanically isolated second ground line of the second inductive structure.

Abstract: In a first inductive structure, a first data coil includes: a first portion for conducting a first common mode current in a first direction; and a second portion for conducting a second common mode current in a second direction opposite the first direction. The first and second portions of the first data coil are connected at a first node. In a second inductive structure, a second data coil includes: a first portion for conducting a third common mode current in the first direction; and a second portion for conducting a fourth common mode current in the second direction. The first and second portions of the second data coil are connected at a second node galvanically isolated from the first node. The first, second, third and fourth common mode currents are induced by a common mode transient.
