Abstract (en)

[origin: EP2966661A2] First and second paths of the primary-coil of the transformer are located at different sides of the symmetry-line. First terminals of the first and second paths are first and second ports of the primary-coil. Second terminals of the first and second paths are connected to each other. Two partial paths of the first path are connected to each other by TSV. Two partial paths of the second path are connected to each other by TSV. Third and fourth paths of the secondary-coil of the transformer are located on different sides of the symmetry-line. First terminals of the third and fourth paths are first and second ports of the secondary-coil. Second terminals of the third and fourth paths are connected to each other. Two partial paths of the third path are connected to each other by TSV. Two partial paths of the fourth path are connected to each other by TSV.
