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.
