2014 Poster Sessions : Interface Circuits for a Wireless Image Sensor

Student Name : Stephanie Hsu
Advisor : Ada Poon
Research Areas: Information Systems
A millimeter-scale wirelessly powered image sensor is proposed for minimally invasive in-vivo imaging. The system consists of an endoscopic camera, a custom integrated circuit chip, and a light source. Design considerations for the interface circuitry between the image sensor and the external data receiver include control blocks to reduce standby power consumption, supply voltage segmentation, and data link bandwidth. In addition, the circuit chip contains an LED driver for the light source. The integration of these components and the effect of a limited power budget is discussed in this work.

Stephanie Hsu is a Ph.D candidate in Professor Ada Poon's group in Electrical Engineering. Her research interests are front-end sensing and stimulation circuits and image sensors.
