This paper presents a 10-b 1 MS/s SAR ADC with a proposed triple-charge-sharing technique to reduce switching energy. The proposed technique uses an additional reservoir capacitor, which has 10% of total CDAC size, to recycle 56% of switching energy. The energy-saving efficiency of this technique is most noticeable in MSBs, so the number of the MSBs to apply the technique has been optimized. The prototype of the proposed SAR ADC is implemented in a 28 nm CMOS technology at 1 V supply voltage. Logic power is minimized with 0.4 V supply voltage. The proposed SAR ADC consumes 2.02 μ W and achieves ENOB of 9.15, equivalent to a Walden FoM of 3.55 fJ/conversion-step. |
