Abstract :
An analytical model of the photoresponse of p-n junctions under a point source illumination is presented. The model measures the response of different regions of the pixel in terms of current. Both p-n+ and p-Nwell junction photodiodes were fabricated in a standard UMC 90nm technology and tested. Model and experimental data reveal a similar behaviour.
