In-pixel temperature sensors for dark current compensation of a CMOS image sensor

This thesis describes the integration of temperature sensors into a CMOS image sensor (CIS). The temperature sensors provide the in-situ temperature of the pixels as well as the thermal distribution of the pixel array. The temperature and the thermal distribution are intended to be used to compensate for dark current affecting the CIS. Two...

Low-Power Low-Noise CMOS Imager Design: In Micro-Digital Sun Sensor Application

A digital sun sensor is superior to an analog sun sensor in aspects of resolution, albedo immunity, and integration. The proposed Micro-Digital Sun Sensor (µDSS) is an autonomous digital sun sensor which is implemented by means of a CMOS image sensor, which is named APS+. The µDSS is designed specifically for micro-satellite application which...

Low-Noise CMOS Image Sensors for Radio-Molecular Imaging

This thesis presents the development of low-noise CMOS image sensors for radio-molecular imaging. The development is described in two directions: firstly, from the technology point of view to reduce the pixel noise level, and secondly from the design point of view to reduce the pixel readout circuits noise level. With respect to the SNR and...
