“Golden Gloves” A/D Converter Match, Round 2: Successive-approximation register vs. sigma-delta topology–Power Efficiency

After the seven-round fight back in April 2010 between the successive-approximation register (SAR) analog/digital converter (ADC) and the sigma-delta (S?) ADC, Figure 1, (click here to see the full ...
