Patent ID: 7759801

Claim:
An integrated circuit (IC) having a plurality of metal traces, the IC further comprising: at least part of a first metal trace of the plurality of metal traces comprising a tapered shape, a first position along the tapered shape, and a second position along the tapered shape, the second position spaced from the first position, wherein the first position and the second position along the tapered shape are formed in a metal layer of the IC; and a part of a second metal trace of the plurality of metal traces positioned adjacent to the at least part of the first metal trace and causing capacitance between the at least part of a first metal trace and the part of the second metal trace, the capacitance approximately decreasing in value along the at least part of the first metal trace, wherein one of the first metal trace and the second metal trace comprises a signal line and the other of the first metal trace and the second metal trace comprises a shielding line.
