Abstract

This work presents an improved semi-analytical model developed for photoresponse estimation of a photodiode based CMOS active pixel sensor (APS). We show its use for maximum pixel photosignal prediction and CMOS APS crosstalk (CTK) optimization. Our model reveals the photosignal and the CTK dependence on the pixel geometrical shape and the pixel arrangement within the array. It brings out clearly the possibility of a design enabling maximum response and/or minimum CTK. It can be used, therefore, as a predictive tool for design optimization.
