Abstract

Official abstract text for this publication.

A common mode noise reduction circuit works with a transmission signal output circuit that has a first and a second output terminals and transmits differential signals from the first and second output terminals. The common mode noise reduction circuit includes: a first generating circuit to generate electric current to input to or receive electric current from the first output terminal; a second generating circuit to generate electric current to input to or output receive electric current from the second output terminal; and a control circuit to control the first and second generating circuits so that in synchronism with a drive control clock of the transmission signal output circuit, the first and second generating circuits generate current pulses to reduce common mode noise of the differential signals to be transmitted.

First claim
