Patent ID: 6992537

Claim:
A receiver for receiving differential signals, said receiver comprising: a noise reduction circuit for eliminating noise from a differential signal transmitted through a differential transmission line; and a data recovery circuit for recovering data from a differential signal outputted from said noise reduction circuit, wherein said noise reduction circuit comprises: common-mode chokes for reflecting common-mode noise superimposed on an input differential signal; and a common-mode noise reduction circuit for directing the common-mode noise reflected by said common-mode chokes to a low potential point of said common-mode noise reduction circuit, said common-mode noise reduction circuit comprising a plurality of terminal resistors between the differential transmission line and said common-mode chokes and between said common-mode chokes and said data recovery circuit; wherein said common-mode noise reduction circuit comprises: first and second resistors as said plurality of terminal resistors, said first and second resistors being connected in series with each other and in a parallel connection between the differential transmission line and said common-mode chokes; and third and fourth resistors to which a power source voltage is applied, said third and fourth resistors being connected in series with each other; and wherein a node between said first and second resistors and a node between said third and fourth resistors are connected to each other.
