  • Publication number: 20230401167
    Abstract: A transfer device for a differential bus system. The transfer device includes a first bus connection and a second bus connection for connection to a transfer medium of the differential bus system, a transmitting device that is connected and/or connectable to the first bus connection and the second bus connection, and an impedance adaptation circuit that is designed to influence an impedance at the first bus connection and/or at the second bus connection.

  • Publication number: 20230223931
    Abstract: An attenuating device for a bus of a controller area network bus system based on differential voltage signals. The bus has first and second bus lines, having an attenuating circuit that provides a variable electrical resistance value between the first and second bus lines and that is operable in at least three circuit states. In a first circuit state, the first and second bus lines are connected via an attenuating resistor having a first resistance value. In a second circuit state, the first and second bus lines are connected via an attenuating resistor having a second resistance value. In a third circuit state, the first and second bus lines are connected via an attenuating resistor having a third resistance value. The first resistance value is lower than the second resistance value. The second resistance value is lower than the third resistance value.

  • Patent number: 11601301
    Abstract: A transceiver device for a bus system and a method for reducing conducted emissions. The transceiver device has a transmitting stage for transmitting a transmit signal to a first bus wire of a bus of the bus system, in which bus system an exclusive, collision-free access of a user station to the bus of the bus system is at least temporarily ensured, and for transmitting the transmit signal to a second bus wire of the bus, a receiving stage for receiving the bus signal transmitted on the bus wires, and an emission reduction unit for controlling a switch-on path of a first stand-off device in the transmitting stage as a function of whether or not a dominant stage of the transmit signal occurs.

  • Publication number: 20220400029
    Abstract: A transmitting/receiving device for a bus system and a method for reducing an oscillation tendency in the transition between different bit states. The transmitting/receiving device has a transmitting stage for transmitting a transmission signal to a first bus wire of a bus of the bus system and for transmitting the transmission signal as an inverse signal to a second bus wire of the bus, and an asymmetry reduction module for reducing an asymmetry of bus signals arising in the bus wires. The asymmetry reduction module includes a polarity reversing diode, whose cathode is connected to the cathode of a reverse polarity diode of the transmitting stage. The asymmetry reduction module switches a potential of the cathode of the polarity reversing diode to a potential that is greater than or equal to a level of a recessive bus state.

  • Patent number: 11218335
    Abstract: A transmission/reception device for a bus system, and a method for reducing conducted emissions, are provided. The transmission/reception device has a transmission stage that has a first and a second transmission block, the first transmission block being configured to transmit a transmitted signal onto a first bus wire of a bus of the bus system, in which bus system exclusive, collision-free access by a subscriber station to the bus of the bus system is at least temporarily guaranteed, and the second transmission block is configured to transmit the transmitted signal onto a second bus wire of the bus; a reception stage for receiving the bus signal transferred on the bus wires; and an emissions reduction unit for controlled switching in of a capacitance unit in parallel with the second transmission stage in order to reduce conducted emissions of the transmission/reception device.
