Abstract
The invention relates to a receiver for a differential data bus with two resistive branches (), with a differential amplifier with two transistors (), with a resistor (), and with a control logic () that controls a switch () with which a current from a current source () is switchable to either side of the resistor (), which resistor couples the two transistors (), and with two operational amplifiers () which are coupled to the two transistors () of the differential amplifier with opposite poles, in which receiver the control logic detects from the output signals of the two operational amplifiers () whether a '0' or a '1' is expected on the bus and which receiver sets the switch () accordingly so that a comparison with the received bus signal is made.
