Thakor Lab YouTube page       VLSI & Instrumentation Head-Mounted Imager  Abstract   The motivation for this project is to develop imagers for head mounted imaging in awake and behaving rats. This ties in with our research on imaging and the long term goal is to monitor functional and anatomical information from the brain over a long period of time. We are working on characterising different CMOS photodiodes structures for the optimal performance in terms of sensitivity, noise and dark current. We are also working on novel high-sensitivity, low noise active pixel designs to develop CMOS imagers rivaling CCD sensors. Test chips have been fabricated and are under active characterization.   Sub Topics Potentiostat Neuropotential Interface Head-Mounted Imager RF Telemetry & Power Harvesting Left: Micrograph of test chip with several photodiode and pixel structure).
