Abstract
Semiconductor device comprising a metal circuit with two parts wound into spirals which are formed such that the branches of one of the parts and the corresponding branches of the other part lie on either side of a median longitudinal region and are symmetrical with respect to this region. A common junction connects the inner ends of the parts and lies across the median longitudinal region and the intermediate junctions between the branches of one of the parts pass above or below the intermediate junctions between the branches of the other part. A common external connection is connected to the common junction and separate external connection are connected respectively to the outer ends of the wound parts. The wound parts constitute two symmetrical metal windings formed between the common connection and the separate connection, respectively, and constituting symmetrical inductors.
