Abstract

The invention relates to an LVDS driver for small supply voltages, particularly of less than 2.0 V, for producing a differential output signal (Pout, Nout), having a pull-up transistor (P3, P4) and a pull-down transistor (P1, P2), respectively, for switching the output voltages which are output at the outputs (Pout, Nout). An optimum switching response and hence an undistorted differential signal can be produced by virtue of the pull-up and pull-down transistors (P1–P4) being in the form of PMOS transistors.
