MSc thesis project proposal
A Power-Optimized Cable Driver for Miniature Ultrasound Probes
- Ultrasound imaging is based on pulse-echo measurements: a transducer sends an acoustic pulse into the medium, after which the resulting echo signals are recorded to render an image. In miniature ultrasound probes (e.g. endoscope- or catheter-based devices), the received echo signals need to be sent across a thin micro-coax cable to an imaging system.
- This project explores the design of a suitable cable driver (MHz bandwidth, >80dB DR), focusing on compact and power-efficient amplifier architectures. An example of an earlier implementation from our group can be found in . In this project, we aim to improve the DR and power efficiency.
- The project includes the design, tape-out and measurement of a prototype chip.
