ABSTRACT:
A method for impedance matching between differential vias and associated transmission lines is provided. The method includes: deducing a relationship of a space between the differential vias, and a radius of the differential vias while a characteristic impedance of the differential vias matches a characteristic impedance of the differential transmission lines; and determining the space and the radius according to the relationship between the space and the radius.
