Abstract: An integrated transformer includes a primary winding and a secondary winding each having a spiral planar arrangement coils. A dielectric portion of dielectric material is interposed between the primary winding and the secondary winding. A field plate winding is electrically coupled with the primary winding. The field plate winding includes at least one field plate coil having a first lateral extension greater than a second lateral extension of a primary outer coil of the primary winding. The field plate coil is superimposed in plan view to the primary outer coil of the primary winding.
