Date May 23, 1996In a driving stage for driving the two differential amplifier output stages of a subscriber line interface circuit, the driving stage is adapted to generate four driving currents in dependence on, on the one hand, transversal and longitudinal signals incoming to the driving stage and, on the other hand, a reference current, and to supply these driving currents in pairs to the two inputs of the differential amplifier output stages, all four of the driving currents being larger than zero. |
