Energy-efficient and area-efficient switching scheme based on multi-reference for SAR ADC
A novel multi-reference capacitor switching scheme for ultralow power successive approximation register (SAR) ADCs is proposed. By using 5 references, the proposed switching scheme only dissipates 10.6 CVREF average energy and requires 256 unit capacitors, which are reduced by 99.2% and 87.5%, compared to the conventional structure. Besides, the common-mode voltage of the comparator input is ap...
