Abstract
An asymmetric differential inductor includes first and second conductive wirings spirally disposed on a substrate having a first input terminal, a second input terminal, a ground terminal, and a central conductive wiring. The central conductive wiring has a central contact connecting the ground terminal and a central end away from the ground terminal. The first conductive wiring extends across the central conductive wiring and has a first contact connecting the first input terminal and a first end connecting the central end. The second conductive wiring extends across the central conductive wiring and interlaces with the first conductive wiring and has a second contact connecting the second input terminal and a second end connecting the central end. Corresponding portions of wiring sections of the first and second conductive wirings at opposite sides of the central conductive wiring are asymmetrical to one another to thereby save substrate space and facilitate circuit layout.
