| 英文摘要 | A method and system for implementing nonlinear transmitter equalization may employ a feed-forward equalizer that applies transition-dependent delays at each tap. Each delay element in a delay line may include independent controls for the delays to be applied to rising transitions and for the delays to be applied to falling transitions. Different delays may be applied to transitions between any two levels in a signal that is encoded using three or more analog levels. Different amounts of weighting may be applied to the output of each delay element in the delay line by respective tap weighing elements. A combiner circuit may generate an output for the equalizer as a linear combination of the weighted outputs of the delay elements. The output of the equalizer may be an input to a vertical cavity surface emitting laser (VCSEL) and may compensate for a nonlinearity of the VCSEL. |
