Closely-spaced bonding wires may be used in a variety of different packaging applications to achieve improved electrical performance. In one embodiment, two adjacent bonding wires within a wire grouping are closely-spaced if a separation distance D between the two adjacent wires is met for at least 50 percent of the length of the shorter of the two adjacent wires. In one embodiment, the separation distance D is at most two times a diameter of the wire having the larger diameter of the two adjacent wires. In another embodiment, the separation distance D is at most three times a wire-to-wire pitch between the two adjacent wires. Each wire grouping may include two of more closely-spaced wires. Wire groupings of closely-spaced bonding wires may be used to form, for example, power-signal-ground triplets, signal-ground pairs, signal-power pairs, or differential signal pairs or triplets.
