A Highly-Scalable Thermal-Diffusivity-Based Temperature Sensor

A highly digital temperature sensor, based on the thermal diffusivity of silicon, for thermal management applications has been reported. Recently, Thermal-Diffusivity based temperature sensors have undergone a radical change from an analog-based readout architecture to a more digital VCO-based one. However the more digital approach led to...

Integrating a Temperature Sensor into a CMOS Image Sensor

Dark current noise in image sensors is highly sensitive to temperature, and a difference in temperature in image sensors can be seen in the image as a non-uniform noise source. Many CMOS image sensors are integrated in mobile devices and lack a physical shutter to generate dark frame subtraction to compensate for dark current noise. In this...
