Abstract:
1. A layout structure, which comprises: a first layout layer; a second layout layer, which is substantially parallel to the first layout layer; and, a plurality of traces, each trace carrying a signal, and the plurality of signals having a phase difference between each other; wherein two neighboring traces configured on the same layer of the first layout layer and the second layout layer have a respective horizontal coupling capacitance in between, two neighboring traces configured on different layers of the first layout layer and the second layout layer have a respective vertical coupling capacitance in between, and each of the plurality of traces have a substantially equal total coupling capacitance wherein the total coupling capacitance is defined by the respective horizontal coupling capacitance and the respective vertical coupling capacitance; wherein each of the traces comprises a first section, a second section, a third section and a fourth section.
