COUPLING ON-DIE INDUCTORS FOR RADIO-FREQUENCY APPLICATIONS

摘要

A circuit includes a dielectric layer, a first via residing in the dielectric layer, a second via residing in the dielectric layer, and an inductor. The inductor includes a first inductor element and a second inductor element. The first inductor element is formed by a first transmission line including a plurality of segments defined between a first end and a second end thereof. The second inductor element is formed by a second transmission line including a plurality of segments defined between a first end and a second end thereof. A first port is defined by one segment of the plurality of segments of the second transmission line, wherein current flows in the inductor in the same direction from a second port defined at the first end of the first transmission line to the first port, and from the first port to a third port defined at the second via.
