<p>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 for the common mode noise within frequency scope of several GHzs without affecting the differential mode signals and improves manufacturing process miniaturization to decrease cost.</p> |
