A pre-setting based sub-radix-2 approximation technique for multi-bit/cycle successive-approximation-register (SAR) analog to digital converters (ADCs) is proposed in this paper. The proposed approximation technique enhances the conversion speed and relieves the power hungry reference voltage buffer...
