A balanced twist design for differential small signal pairs which is balanced in terms of resistance, capacitance and process variance. In the twist design of the present invention, each routing (6, 10) passes through two layers of metal. In addition, each routing (6, 10) passes through the same number of vias (9, 13, 14, 15), and experiences the same number of bends. Each routing (6, 10) is also exposed to the same sidewall crosstalk since the length and width of each routing (6, 10) in both metal layers is approximately the same. As a result, the new twist design reduces signal degradation, enhances signal separation, and allows increased clock speed of the integrated circuit.
