Abstract

The present invention relates to an integrated transformer configuration having a first coil formed from an electrically conductive material having a spiral course with an essentially rectangular cross section. The transformer has a second coil with a spiral course. The first and the second coils are arranged such that they are electrically insulated from one another. The ratio between the height and the width of the rectangular cross section of the first coil is greater than 1.
