Abstract

An integrated circuit (IC) for driving a light emitting semiconductor device is provided. The IC includes an input stage configured to receive a first input signal with a first differential pair of bipolar transistors and a second input signal with a second differential pair of bipolar transistors and to provide a pre-driver output signal being a superposition of the first input signal and the second input signal and an output stage including a third differential pair of bipolar transistors for receiving the pre-driver output signal of the input stage and for driving the light emitting semiconductor device in response to the pre-driver output signal, wherein the IC is configured to pre-distort the pre-driver output signal of the input stage so as to compensate a signal distortion of the output stage.
