Title:
TWO LAYER TRANSFORMER
Document Type and Number:
Japanese Patent JP2011040509
Kind Code:
A
Abstract:
To provide a structure for a symmetrical transformer, including two coils each having at least two turns so as to be achievable in two conductive layers, in which terminals of the coils are located at opposite sides of the structure.
A symmetrical transformer with a stacked coil structure includes two coils each having at least two turns. The structure includes four identical basic elements, each basic element providing a conductive path for part of the coils. The terminals of the transformer are located at opposite sites of the structure so that the structure can be easily connected in a chain. The invention also relates to a semiconductor device comprising such a structure.
