ABSTRACT:
An isolation transformer is provided by a primary conductor formed on an insulating layer above a secondary conductor formed on a chip therebelow, with flux lines coupling between the primary and secondary conductors to provide transformer action through the insulating layer therebetween. The primary is formed by a serpentine pattern having a plurality of parallel strips transverse to a plurality of parallel strips forming the secondary conductor. The secondary conductor may be formed on an extra insulating layer on the chip substrate.
