LINEARIZATION OF DIGITAL-TO-ANALOG CONVERTERS (DACS) AND ANALOG-TO-DIGITAL CONVERTERS (ADCS) AND ASSOCIATED METHODS

摘要

The present embodiments introduce an approach for designing perfectly linear DACs using non-ideal components. The approach may eliminate the nonlinearity of the DAC and remove the conventional trade-offs between performance and complexity. One embodiment includes receiving an input digital signal, segmenting the input digital signal into a plurality of segments, each segment being thermomete -coded, generating a redundant representation of each of the plurality of segments, defining a plurality of redundant segments, performin a redundancy mapping for the plurality of segments, defining redundantly mapped segments, assigning a probabilistic assignment for redundantly mapped segments, converting each redundantly mapped segment into an analog signal by a subdigital-to-analog converter (DAC), and combining the analog signals to define an output analog signal.
