摘要： A differential signal line structure is disposed on a substrate including a signal layer, a filter layer and a grounding layer. The signal layer, the filter layer and the grounding layer are arranged from up to down and in parallel manner. The differential signal line structure accordingly includes a differential signal line group, a first wire and a first grounding circuit; the differential signal line group is disposed in the signal layer; and the first wire is disposed in the filter layer and is arranged in a corresponding position right underneath the differential signal line group. The first grounding circuit is disposed in the grounding layer and is electrically connected to an end point of the first wire through a first via.

摘要： A differential mode transmission line with a weak coupling structure is presented. The differential mode transmission line with a weak coupling structure includes a first transmission line and a second transmission line. The first transmission line includes a first wiring portion, a second wiring portion, and a third wiring portion. The second transmission line also includes a first wiring portion, a second wiring portion, and a third wiring portion. The wiring portions of the present disclosure are connected through connection portions, and the connection portions are designed as a corner structure. Due to the characteristics of the corner structure of the present disclosure, a pitch between the second wiring portions is greater than that between the first wiring portions or the third wiring portions, thereby generating a weak coupling structure to suppress common mode noises.

摘要： A delay line structure includes a serpentine delay line, a first grounding guard trace and a second grounding guard trace. The serpentine delay line is disposed in a layout layer of a substrate in a manner of extending from an input end to an out put end in serpentine so as to form at least a first coupling area having a first opening toward a first direction and at least a second coupling area having a second opening toward a direction opposite to the first direction. The first grounding guard trace is disposed in the layout layer in a manner of extending from the first opening toward the first coupling area and an end of the first grounding guard trace close to the first opening is electrically connected to the grounding circuit through a first via. The second grounding guard trace is disposed in the layout layer in a manner of extending from the second opening toward the second coupling area and an end of the second grounding guard trace close to the second opening is electrically connected to the grounding circuit through a second via.
