Abstract:
The present invention relates to an input circuit for receiving an input signal in an integrated circuit, having a differential amplifier whose first input can have a predetermined reference voltage applied to it and whose second input can have the input signal applied to it, and having a current source for operating the differential amplifier at its operating point, wherein a setting circuit is connected to the current source in order to set the operating point of the differential amplifier in an optimum manner on the basis of the predetermined reference voltage.
