Abstract: A transmitter for establishing communication between a device and a differential network bus includes current driving means connected to each of the two conduction lines of the differential network bus, through a first and second conduction paths of the transmitter; at least one unidirectional current regulator for extracting a first current equal to a known ratio of a parasitic current circulating through the first conduction path, with a direction inverse to the driving current through the conduction path connected to one of the lines of the differential bus; means for obtaining, from the first current, a second current with a magnitude equal to the original magnitude of the parasitic current; and means for introducing the second current into the second conduction path connected to the other line of the differential bus.

Abstract: A transceiver circuit for communicating data over a CAN bus having a first and second bus line the transceiver circuit comprising: a data input port, a data output port, a CAN-bus transceiver unit having a receive data output port for providing data received from the CAN-bus, and a transmit data input port for receiving data to be transmitted to the CAN-bus; a control input port for receiving a control signal indicative of whether transmission of data from this transceiver circuit to the CAN-bus is allowed or prohibited; a filtering circuit adapted for filtering the control signal received on the control input port and for providing a filtered control signal; a logic circuitry adapted for configuring the CAN-bus transceiver unit in receive mode based on the debounced control signal irrespective of ongoing communication on the CAN-bus.
