技術說明

本發明之主要目的係提供一種具接地防護線之平坦螺旋形延遲線結構，該平坦螺旋形延遲線之目的在於避免於平坦螺旋形延遲線內設置貫穿孔，而同時又必須能夠有效的抑制平坦螺旋形延遲線的串音雜訊干擾。 相較於習知之未置入接地防護線之平坦螺旋形延遲線，本發明利用兩條僅一端接地的接地防護線，即可抑制串音雜訊干擾，而相較於置入兩端接地防護線之平坦螺旋形延遲線，由於本發明之平坦螺旋形延遲線內部並不需要設置貫穿孔，因此能夠輕易的解決長久以來無法克服的平坦螺旋形延遲線小型化難題。 A delay line structure is provided according to the present invention. The delay line structure does not need the installation of via inside the flat spiral delay line and effectively reduces the crosstalk noise disturbance in the flat spiral delay line. When compared with the delay line in prior art, which is not installed with grounding guard traces, the present invention avoids the crosstalk noise disturbance by means of two grounding guard traces connecting to the ground with an end. When compared with the serpentine delay line having a guard trace with both ends connecting to the ground in prior art, since there is no need to install the via inside the flat spiral delay line according to the present invention, the problem of being unable to downsize the flat spiral delay line is easily solved.
