Title:
複数のインターリーブ集積回路トランス
Document Type and Number:
Japanese Patent JP2004531089
Kind Code:
A
Abstract:
Each coil of a transformer is partitioned into two or more parallel segments. The multiple segments of each coil are interleaved with each other to form a coplanar interleaved transformer that has a greater coupling efficiency than a non-segmented coplanar interleaved transformer. In a preferred embodiment, the multiple segments are of reduced width, so that the interleaved coils consume substantially the same area as the non-segmented coplanar interleaved transformer, thereby maintaining the same inductance as the non-segmented transformer. To provide for maximum efficiency, each segment of each coil is embodied so as to have substantially equal length as each other segment of the coil.
