A Low-Power Area-Efficient SAR-Assisted Hybrid ADC for Ultrasound Imaging

This thesis presents a Low-Power Area-Ecient SAR-Assisted Hybrid ADC for ultra-<br/>sound imaging systems. This ADC combines a 5-bit SAR ADC per channel with a 4-bit single-slope ADC that produces the converter's LSBs and is implemented using shared hardware. The number of unit capacitors of the proposed ADC is about 1/16th of that of a 9-bit...
