45-nm SOI CMOS Bluetooth Electrochemical Sensor for Continuous Glucose Monitoring
(University of Waterloo, 2018-08-21)Due to increasing rates of diabetes, non-invasive glucose monitoring systems will become critical to improving health outcomes for an increasing patient population. Bluetooth integration for such a system has been previously ... -
CMOS Electrochemical Camera for Biological Cell Impedance Imaging
(University of Waterloo, 2019-07-19)Many biomedical applications require observing the response of biological cells to various stimuli and conditions. Typical optical imaging systems for observing cells require labelling cells with fluorescent molecules. ... -
A High-Resolution CMOS Single-Photon-Counting Spectrographic X-Ray Imager
(University of Waterloo, 2023-09-01)Digital X-ray imagers for clinical mammography and computed tomography (CT) have been recently taking advantage of the noise-rejection properties of single-photon-counting (SPC) architectures. However, conventional SPC ... -
A High-Resolution Direct-Conversion CMOS X-Ray Imager with Code-Division-Multiplexed Readout
(University of Waterloo, 2023-04-21)This thesis presents the design and characterization of a high-spatial-resolution direct-conversion X-ray imager built using complementary metal-oxide-semiconductor (CMOS) technology integrated with an amorphous-selenium ... -
Hybrid Amorphous Selenium-CMOS Photon-Counting X-ray Imager
(University of Waterloo, 2018-05-23)Many medical imaging modalities, such as mammography and micro-computed tomography, utilize digital X-ray imagers to observe human anatomy. Direct digital X-ray imagers rely on a sensor layer (typically a photoconductor) ... -
Hybrid Amorphous-Selenium/CMOS Low-Light Imager
(University of Waterloo, 2018-07-18)This thesis aims to demonstrate a low-light imager capable of moonlight-level imag- ing by combining a custom-designed complementary-metal-oxide-semiconductor (CMOS) pixel array with amorphous selenium (a-Se) as its ... -
