Method and apparatus of power ring positioning to minimize crosstalk

1. A method comprising:

generating an array of fingers between a power ring and a die;

applying a signal wire between a bond pad of the die and a particular finger of the array of fingers; and

applying a shielding wire between an adjacent bond pad and the power ring, such that the shielding wire is longer than the signal wire and does not couple to any of the array of fingers.

2. The method of claim 1 wherein the shielding wire is placed between adjacent ones of the signal wire to minimize crosstalk between the adjacent ones of the signal wire.

3. The method of claim 1 further comprising creating at least one of the shielding wire and the signal wire from at least one of a metal including copper, aluminum, silver, and an aluminum doped alloy.

4. The method of claim 1 wherein the array of fingers are moved directly adjacent to the die, such that a length of the signal wire decreases by at least 20% from that of a design in which the power ring is located between the die and the array of fingers.

5. The method of claim 1 further comprising decreasing a silicon area of the die because separate shielding input/output devices are not required when the shielding wire does not couple to any of the array of fingers.

6. The method of claim 1 further comprising minimizing an effect of a crosstalk when the shielding wire is between two signal wires on either side of the shielding wire.

7. The method of claim 6 wherein the crosstalk is further reduced by shortening the signal wire from a design in which the power ring is located between the die and the array of fingers.
