一種共模雜訊抑制電路,應用於差動訊號之傳輸應用上,對於傳輸線所傳送之差動訊號進行共模雜訊抑制。本發明以電磁耦合原理結合接地結構形成電感-電容共振架構,抑制差動訊號於寬頻下之共模雜訊,同時利用差動傳輸線設計,於寬頻下保持差模訊號之低損耗。據此,該共模雜訊抑制電路能夠在不影響差模訊號的情況下,於數GHz的頻率範圍內對共模雜訊進行寬頻抑制,並且改善製程微縮化之問題,以進一步降低成本。
A common mode noise suppression circuit applicable to differential signal transmission performs common mode noise suppression with respect to differential signals transmitted by a transmission line. An inductance-capacitance resonant structure is formed based on electromagnetic coupling combining a ground structure to suppress common mode noise of differential mode signals at broadband meanwhile keeping low loss of the differential mode signals at broadband via differential transmission lines. By this, the common mode noise suppression circuit performs broadband suppression with related to the common mode noise within a frequency scope of several GHz without affecting the differential mode signals and improves manufacturing process miniaturization to decrease cost.
