ABSTRACT:
A system and method for improving the linearity of a digital-to-analog converter (DAC) is provided. In one embodiment, the system comprises a digital waveform generator that generates a digital sequence associated with a desired analog waveform and a pseudo-random noise component that provides a pulse shaped band limited pseudo-random noise sequence. The system further includes a combiner configured to combine the digital sequence and the pulse shaped band limited pseudo-random noise sequence and provide the combined sequence to the DAC.
