Abstract
A method for a mix mode driver to accommodate traces of different lengths includes sequentially shifting values of a data signal to a number of stages and sequentially amplifying the values of the data signal at least one stage. Depending on the length of trace for the data signal, the method further includes providing at least one amplifying coefficient to at least one stage and coupling a subset of the stages to an adder. The method finally includes outputting the data signal from the adder to the trace.
