Binary scaled error compensation
WebApr 20, 2013 · Figure 1 shows the architecture of the ADC we proposed. In a SAR ADC, a differential architecture is often employed to have a good common-mode noise rejection and achieve a high accuracy. To achieve a better linearity, a binary-weighted capacitor carry including C 0–6, C 0b, C 3b, C 4b and C dummy is employed in the DAC. Such C 0b, C … WebFeb 11, 2010 · Abstract: This paper presents a 10 b SAR ADC with a binary-scaled error compensation technique. The prototype occupies an active area of 155 × 165 ¿m 2 in 65 nm CMOS. At 100 MS/S, the ADC achieves an SNDR of 59.0 dB and an SFDR of 75.6 dB, while consuming 1.13 mW from a 1.2 V supply. The FoM is 15.5 fJ/conversion-step.
