Driver for a shared bus, in particular a LIN bus
A driver for a shared bus, such as a LIN bus, having a supply node (Vbat), a bus node (LIN), a transmit data input node (TX) and a receive data output node (RX), said driver comprising: a pull-up circuitry between the supply node and the bus node, driver circuitry (100) having a control input connected to the transmit data input node, feedback circuitry (200) configured to provide feedback from the shared bus to the control input of the driver circuitry; said feedback circuitry comprising copy circuitry (210) configured to obtain at least one copy signal representative for a signal on the bus node, filter circuitry (220) configured to low-pass filter the at least one copy signal, derivative circuitry (230) configured to obtain at least one derivative signal representative for the speed at which the signal on the bus node varies.

Method and apparatus for outputting signals
This application relates to a method and apparatus for outputting signals. In one aspect, the apparatus includes a signal control unit configured to generate two or more control signals upon two or more conditions, which respectively correspond to the two or more control signals being satisfied. The apparatus also includes a signal output unit configured to output a final output signal depending on the two or more control signals upon an input signal being inputted into the signal output unit.
