技術說明

一種差模平坦螺旋形延遲線結構係用以佈設於一基板。基板具有一介電基材層、一佈線層與一接地層。上述之差模平坦螺旋形延遲線結構包含佈設於佈線層之ㄧ螺旋形延遲線組與至少一接地防護線。螺旋形延遲線組依序包含一第一外平直段、一第一外彎折段、一內螺旋區、一第二外彎折段與一第二外平直段。其中，內螺旋區係在第一外平直段與第二外平直段之間反覆彎折形成複數個內彎折段與複數個內平直段。接地防護線係設置在第一外平直段、內平直段與第二外平直段之間，且第一外彎折段、內彎折段、第二外彎折段之寬度係分別小於第一外平直段、內平直段、第二外平直段之寬度。 The present invention relates to a differential flat spiral delay line structure, and more particularly to a differential flat spiral delay line structure with grounding guard traces and strong coupling line parts. The following describes a differential flat spiral delay line structure of the prior art. Firstly, crosstalk noise disturbance is generally resulted between an adjacent pair of the straight sections in the spiral delay lines, thereby affecting a waveform of a received signal, which leads to misinterpretation on a voltage level of a digital received signal. Secondly, due to unequal lengths at the outer and inner bent sections of the spiral delay lines 11 and 12, signal synchronizing for transmission the signals at the same rate is hard to achieve. Although grounding guard traces are applied to reduce the crosstalk noise disturbance, the result is still not ideal.
