Abstract
Aspects of the disclosure provide an integrated circuit (IC) chip with an on-chip transformer. The on-chip transformer includes a primary inductor and a secondary inductor. The primary inductor is configured to have a first-primary coil portion formed of a first patterned metal trace disposed in a first metal layer and a second-primary coil portion formed of a second patterned metal trace disposed in a second metal layer. The secondary inductor is configured to have a first-secondary coil portion formed of a third patterned metal trace that interleaves with the first patterned metal trace in the first metal layer and a second-secondary coil portion formed of a fourth patterned metal trace that interleaves with the second patterned metal trace in the second metal layer.
