Abstract :
Although mismatch-shaping multi-bit DACs offer many advantages over single-bit DACs in delta-sigma data converters, most of the presently known mismatch-shaping DAC architectures involve a large amount of digital processing. This paper presents digital structures that implement previously published tree-structured mismatch-shaping DAC algorithms yet offer significant reductions in the digital processing
