description A Low Voltage Differential Signaling Driver with Pre-emphasis and including a primary stage having a first switching circuit providing an output representing a sequence of pulses at a predetermined current level, a secondary stage having a second switching circuit arranged to provide an additional current level for the pulses, and a control circuit arranged to provide control signals for controlling the first and second switching circuits. The control circuit detects a difference in level between two consecutive pulses of the sequence and provides accordingly control signals to the first and second switching circuits. The control signals are such that when two consecutive pulses of the sequence are different, the additional current level is added to the predetermined current level, whilst when two consecutive pulses of the sequence are identical, the additional current level is subtracted from the predetermined current level.
