技術摘要 / Our Technology: |
本發明有關於一種電磁雜訊抑制電路,其包括有一第一基板、一第一接地面及至少一傳輸線,第一基板之上表面設置傳輸線而下表面設置第一接地面,第一接地面包括有一第一分散式耦合結構,第一分散式耦合結構與傳輸線間可等效形成一電感-電容共振電路,藉此,抑制電路採用分散式耦合結構抑制特定頻帶內之電磁雜訊,以避免干擾到傳輸線上所傳送的訊號,並減少雜訊所造成之電磁輻射。
An electromagnetic noise suppression circuit is provided. The suppression circuit comprises a first substrate, a first grounding plane and at least one transmission line. The transmission line is configured on a top surface of the first substrate and the first grounding plane is configured on the bottom surface of the first substrate. The first grounding plane comprises a first distributed coupling structure. The first distributed coupling structure and the transmission line can be equivalent to an inductor-capacitor resonant circuit. The electromagnetic noise within a designated frequency band can be suppressed by the distributed coupling structure of the electromagnetic noise suppression circuit to avoid interfering the signal transmitted by the transmission line and the electromagnetic radiation induced by the electromagnetic noise.
