Abstract:
1. A laser driver apparatus, comprising: a single laser driver comprising a plurality of digital-to-analog converters; a decoder that communicates electronically with said plurality of digital-to-analog converters; at least one threshold level and at least one undershoot level, wherein said at least one threshold level and said at least one undershoot level are digitally combined into a single output with respect to said single laser driver to reduce an output capacitance of said single laser driver and minimize a circuit power of said single laser driver resulting in a faster and higher fidelity signal thereof; and wherein thermometer decoding of said at least one threshold level and said at least one undershot level via said decoder permits usage of said single laser driver if said at least one threshold level and said at least one undershoot level are digitally combined such that at least one least significant bit of at least one digital-to-analog converter among said plurality of digital-to-analog converters maps to a same bit driver as at least one most significant bit of at least one other digital-to-analog converter among said plurality of digital-to-analog converters.
