  • Patent number: 8054911
    Abstract: A method is provided for edge formation of signals and transmitter/receiver component for a bus system. A transmitter/receiver component for a bus system comprises a driver transistor, which is to be looped between a bus line of the bus system and a reference potential and is used to output signals on the bus line, a control unit for the driver transistor, a high-frequency interference detector, which is configured in such a way that it detects a high-frequency interference level on the bus line of the bus system, whereby the control unit is configured in such a way that it controls the driver transistor, depending on the detected high-frequency interference level, in such a way that an edge steepness of the output signals increases when the high-frequency interference level on the bus line increases, and an edge steepness of the output signals decreases when the high-frequency interference level on the bus line decreases.

  • Publication number: 20080211114
    Abstract: A semiconductor component is provided, particularly for LIN bus systems, having an integrated circuit, which on a top side has a plurality of terminal pads for coupling and/or decoupling of electrical signals, and having a plurality of electrically conductive contact reeds, which are electrically connected at least partially by connecting bonding wires to the respectively assigned terminal pads of the integrated circuit. Also, a connecting bonding wire and a shielding bonding wire is provided, which is disposed with both ends on a uniform electric potential, particularly on one of the contact reeds.
