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...

In-Pixel temperature sensors with an accuracy of ±0.25 °C, a 3σ variation of ±0.7 °C in the spatial domain and a 3σ variation of ±1 °C in the temporal domain

This article presents in-pixel (of a CMOS image sensor (CIS) temperature sensors with improved accuracy in the spatial and the temporal domain. The goal of the temperature sensors is to be used to compensate for dark (current) fixed pattern noise (FPN) during the exposure of the CIS. The temperature sensors are based on substrate parasitic...
