Abstract
A differential amplifier is described comprising an input branch for receiving differential and common mode input signal components; an output branch providing differential and common mode output signal components; and the differential amplifier being adapted to set a relationship between the magnitude of the common mode output signal component level of the amplifier with respect to the magnitude of the common mode input signal component level to the input stage so that the common mode output signal component level intrinsically follows the common mode input signal component level as a common mode follower without using feedback control of the common mode output signal component. Also an asymmetrical amplifier is described which may be advantageously used as a component of the differential amplifier.
