### Abstract

This paper presents a new subrange analog-to-digital converter (ADC): a binary-search coarse ADC + a SAR fine ADC. The binary-search ADC improves conversion speed and gives coarse capacitors longer settling time. This ADC uses an RC hybrid DAC to reduce the unit capacitor count by 2. The rotation function of coarse capacitors enhances capacitor array linearity. The prototype in 90-nm CMOS only occupies an active area of 0.06 mm ^{2}. From a 0.9-V supply, the power consumption is 0.32 and 0.58 mW at 10 and 25 MS/s, respectively. At 10 MS/s, the peak ENOB is 10.2 bit. At 25 MS/s, the peak ENOB is 9.9 bit and FOM is 29 fJ/conversion-step.
