Claim Text:
1. A circuit comprising: a differential via configured to carry a differential signal and including a first via and a second via, the first via having a first-via length and the second via having a second-via length longer than the first-via length, a first plane intersecting the differential via substantially half-way between the first via and the second via, the first plane being substantially perpendicular to a second plane intersecting a first center of the first via and a second center of the second via; and a differential stripline configured to carry the differential signal and coupled to the differential via, the differential stripline including a first trace and a second trace that are broadside coupled to each other over at least a portion of the differential stripline to form a broadside coupled portion of the differential stripline, the first trace being coupled to the first via and having a first-trace length between the broadside coupled portion of the differential stripline and the first via, the second trace being coupled to the second via and having a second-trace length between the broadside coupled portion of the differential stripline and the second via, a trace-length difference between the second-trace length and the first-trace length being approximately equal to a via-length difference between the second-via length and the first-via length, the broadside coupled portion of the differential stripline being offset from the first plane such that the second-trace length is shorter than the first-trace length.
