 A Compact Noise-Shaping SAR ADC for Smart Ultrasound Probes
- 3D ultrasound probes require transducer arrays with >1000 elements. Future ultrasound probes will be smart, i.e. will have a fully digital interface. This means that many compact low-power ADCs will need to operate in parallel to digitize the received echo signals. Small die size and high power efficiency are key requirements for such in-probe ADCs.
- This project aims to extend out previous work on in-probe digitization (see e.g. ) and investigate the use of noise-shaping SAR ADCs for this application.
