Abstract
The present disclosure provides an inductor for suppressing noise in a pair of a first signal and a second signal. The inductor comprises: a first core; a second core adjoined to the first core; a first coil wound around at least a first portion of the first core; a second coil wound around at least a second portion of the second core; and a third core adjoined to the first core and/or the second core and disposed between the first coil and the second coil, wherein the inductor is operable to attenuate both CM noise and DM noise in the first signal and the second signal that pass through the first coil and the second coil, respectively.
