Automotive 8.3 MP CMOS Image Sensor with 150 dB Dynamic Range and Light Flicker Mitigation

Abstract

This paper presents an 8.3 MP image sensor for automotive applications. The sensor has a 2.1 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mu \mathrm{m}$</tex> pixel with overflow to a low gain capacitor and a triple gain readout. This pixel is a further evolution of the 3.0 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mu \mathrm{m}$</tex> pixel presented earlier. The single exposure (flicker free) dynamic range is increased from 96 dB to 110 dB and the SNR stays above 25 dB at each of the transition points up to 125°C. By adding a second exposure the dynamic range reaches 150 dB.
