Abstract (en)
[origin: WO0213373A1] The invention relates to a broad-band driver circuit for transmitting voice and data signals. Said driver circuit comprises a current divider circuit (37) that divides the current generated by a current source (38) in accordance with a voice and data signal received on a signal input (21) into two basic currents (Ib1, Ib2) for controlling a first driver transistor (39) and a second driver transistor (40), said two driver transistors (39, 40) having a similar structure.
