Integrated Inductor Structure and Integrated Transformer Structure

摘要

An integrated inductor structure includes a first spiral coil, a second spiral coil and a connection metal segment. The first spiral coil includes a plurality of metal segments, a bridging segment and first to fourth terminals. The bridging segment connects the metal segments. The second spiral coil has fifth and sixth terminals. The connecting metal segment connects the third and fifth terminals and the fourth and the sixth terminals. The integrated inductor structure uses the first and second terminals as its input and output terminals. The first and third terminals are on a first imaginary line, which passes a central region of a region surrounded by the first spiral coil. The bridging segment and the central region of the region are on a second imaginary line. An included angle between the two imaginary lines is equal to or greater than 45 degrees and equal to or smaller than 90 degrees.
