Abstract
A wide-band common mode filtering apparatus includes at least two cascaded common mode filters with different noise-filtering responses, wherein the cut-off frequency of the wide-band common mode filtering apparatus is at the lowest cut-off frequency of the common mode filters, and the noise-filtering response of the wide-band common mode filtering apparatus is the superposition of the noise-filtering responses of the common mode filters. In one embodiment of the present invention, the wide-band common mode filtering apparatus includes a first common mode filter having a first filtering band, and a second common mode filter having a second filtering band different from the first filtering band. The disclosure of the present technique allows the cascaded common mode filters with different filtering bands to form the wide-band common mode filtering apparatus having an overall filtering band to meeting a new demand.
