In this work, several studies on Total Ionizing Dose effects on Pinned Photodiode CMOS images sensors are presented. More precisely, the evolution of a parasitic signal called Random Telegraph Signal is analysed through several photodiode designs. It is shown that the population of pixels exhibiting this fluctuation depends on the design variants. This population also increases in a different way with the dose: the effects are not same considering a low or high X-rays irradiation. Moreover, a statistical analysis is realized in order to better caracterize the defects responsible for RTS. It turns out that electric field enhancement signature can appear in some specific cases.
