Abstract
An input stage for an LVDS receiver circuit is provided, which includes at least one supply voltage connection as well as a first and a second stage input to be acted upon by a differential input signal pair. The input stage further includes a first and a second differential stage, the stage inputs being directly connected to one input each of the first differential stage and indirectly, via one level-shifting circuit each, to one input each of the second differential stage. According to the present invention, the first and the second differential stage are connected to the supply voltage connection via one transistor each of a third differential stage, the control input of one of these transistors being connected to a measuring path connecting the stage inputs to one another, with the control input of the other transistor being connected to an apparatus/device (arrangement) for providing a reference voltage.
