摘要： A transformer structure includes at least three sections, each corresponding to metal layers of an integrated circuit. A first section of the at least three sections is electrically coupled to a third section with a second section disposed between the first and third sections. The at least three sections includes inductor coils, all of which are wound in a same direction and voltage phase starting at an outer terminal and continuing to an inner terminal of each inductor coil. At least one radial wiring channel passes through a portion of a coil in one of the three sections to provide an external connection to an internal terminal of the coil in at least one of the three sections.
