Photodiode comparison for imaging systems with harvesting capabilities

This paper presents a study on photodiodes dedicated to image sensors which merge imaging and harvesting capabilities. This study has led to a VerilogA model of photodiodes dependent on the properties of the CMOS process, photodiodes geometry and illumination. Such model will be useful to make predictions on the behavior of new architectures of photodiodes used in CMOS image sensors embedding harvesting capability.
