Patent ID: 7013452

Claim:
A multi-layer circuit board comprising: a first via having a signal input location for receiving an input signal, said first via being formed and disposed completely through said multi-layer circuit board; a second via having a signal output location, said second via being formed and disposed completely through said multi-layer circuit board; a first electrical connection between said first via and said second via, forming a first electrical path between said signal input location and said signal output location; and a second electrical connection between said first via and said second via, forming a second electrical path between said signal input location and said signal output location; wherein a first end of said first via is connected to a first end of said second via, and a second end of said first via is connected to a second end of said second via, such that said input signal travels partly in a first direction in said first via and partly in a second direction through said first via, said first direction being opposite that of said second direction; wherein the electrical length of said first electrical path equals the electrical length of said second electrical path, and said first electrical path and said second electrical path have a same starting point and ending point, and wherein any signal degradation, as a function of amplitude loss, between said signal input location and said signal output location attributable to said first via and said second via is substantially eliminated.
