Patent ID: 7095307

Claim:
A device, comprising: a first circuit; a second circuit; and an impedance matching circuit coupled between the first circuit and the second circuit, wherein the impedance matching circuit includes: a first in-silicon inductor spiraling in a first direction, wherein the first in-silicon inductor has a plurality of turns, and a second in-silicon inductor spiraling in a second direction opposite the first direction, wherein the second in-silicon inductor has a plurality of turns, wherein the first in-silicon inductor is interleaved with the second in-silicon inductor, wherein an input of the first in-silicon inductor and an input of the second in-silicon inductor receives a differential signal and an output of the first in-silicon inductor and an output of the second in-silicon inductor produces a differential signal, and wherein a first current in the first in-silicon inductor and a second current in the second in-silicon inductor flow in a same direction in corresponding turns of the first in-silicon inductor and the second in-silicon inductor.
