Abstract
A novel energy-efficient switching scheme for successive approximation register (SAR) analog-to-digital converters (ADC) is proposed in this paper. The average switching energy of the proposed switching scheme can be reduced by 95.3%, compared with the [Formula: see text]-based scheme. Moreover, the linearity has been also improved significantly. Employing the proposed switching scheme, a 10-bit 100[Formula: see text]kS/s SAR ADC is designed in SMIC 0.18-[Formula: see text]m CMOS process. At a 0.6-V supply, the ADC consumes 43.7[Formula: see text]nW. Consequently, the figure-of-merit (FOM) is optimized to 0.58[Formula: see text]fJ/conversion-step.
