US Patent 10355642 Comb terminals for planar integrated circuit inductor

A technique for reducing series resistance of an inductor system, which may increase the quality factor of the inductor system, has been disclosed. An apparatus includes a conductive loop formed from a first conductive layer. The conductive loop comprises a first terminal and a second terminal. The first terminal includes at least one first conductive finger in the first conductive layer. The second terminal includes at least one second conductive finger in the first conductive layer. The at least one second conductive finger is interdigitated with the at least one first conductive finger without directly contacting the at least one first conductive finger. The apparatus may include a serpentine gap in the first conductive layer. The apparatus may include at least one first conductive via coupled to a second conductive layer and coupled the at least one first conductive fingers, respectively.
