Mismatch of the digital-to-analog converter (DAC) elements is the major limitation for Signal to Noise and Distortion Ratio (SNDR) and Spurious Free Dynamic Range (SFDR) in multi-bit Delta Sigma Modulators (DSM). In this brief we extend a previously introduced technique to build an intrinsically lin...
