ABSTRACT:
A high-Q inductor for high frequency, having a plurality of inductor elements formed in a plurality of IC wiring layers with a connection formed therebetween. The directions of the magnetic fields generated by the respective inductor elements are substantially the same. With this construction, the section of the inductor is increased reducing the serial resistance component and an influence of a skin effect in a high-frequency range is eliminated increasing the Q value.
