MSc thesis project proposal
Element-level delta-sigma ADC for ultrasound imaging
- 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.
- In our previous work , we have have developed a new compact ADC that uses the transducer as loop filter. This project aims to further elaborate this idea and develop a higher-resolution version for this innovative ADC.
- The project includes the design, tape-out and measurement of a prototype chip.
