Assignee: REALTEK SEMICONDUCTOR CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a first coil;
a second coil disposed with respect to the first coil; and
a third coil configured to sense a signal on the first coil, wherein a first overlapped area, on a projection plane, of the third coil and the first coil is larger than a second overlapped area, on the projection plane, of the third coil and the second coil, wherein the third coil comprises:
a first trace;
a second trace;
a third trace coupled between the first trace and the second trace;
a fourth trace;
a fifth trace;
a sixth trace coupled between the fourth trace and the fifth trace; and
a seventh trace coupled the first trace and the fourth trace, wherein the first trace, the second trace, the third trace, the fourth trace, the fifth trace, and the sixth trace are disposed at a first metal layer, wherein the seventh trace is disposed at a second metal layer.
