Photoresponse analysis and pixel shape optimization for CMOS active pixel sensors.

Photoresponse analysis and pixel shape optimization for CMOS active pixel sensors.

In this work, a semi-analytical model, based on a thorough analysis of experimental data, is developed for photoresponse estimation of a photodiode-based CMOS active pixel sensor (APS). The model covers the substrate diffusion effect together with the influence of the photodiode active-area geometri...
