Patent attributes
A transformer device includes first conductive segments, second segments, and third conductive segments. The second segments include second conductive segments and first bridging segments. The first bridging segments are connected to the first conductive segments to form a first inductor. The third conductive segments include second bridging segments, and the third conductive segments are connected to the second conductive segments to form a second inductor. The first inductor is located on the second inductor. The first bridging segments and the first conductive segments form first interlaced portions along a first direction. The second bridging segments and the second conductive segments form second interlaced portions along a second direction. The first direction is different from the second direction.
