ABSTRACT:
An inductor structure disposed over a substrate includes a first spiral coil, a second spiral coil and at least a gain pattern. The first spiral coil includes first conducting wires and first connection leads, wherein each first connection lead connects two adjacent first conducting wires. The second spiral coil includes second conducting wires and second connection leads, wherein each second connection lead connects two adjacent second conducting wires. The second spiral coil and the first spiral coil are symmetrically disposed about a plane of symmetry and in series connection to form a spiral coil structure with 2N turns, wherein N is a positive integral, and are spaced from the substrate by different heights to form 2N−1 interlaced zones. The gain pattern is disposed under the first connection lead at the (2N−1)thinterlaced zone counted from the most-outer turn up and electrically connected to the corresponding first connection lead.
