Abstract
Methods and apparatus are described for generating or amplifying a differential signal. The output of a first op amp corresponds to one end of the differential signal. The output of a second op amp corresponds to the other end of the differential signal. The inverting input of the first op amp is coupled to the noninverting input of the second op amp.
