Image sensor Lexicon compiled by Bart Dierickx, version 14nov2009. 1/f noise 1T pixel 1.75T and 1.5T pixels Temporal noise with a dominantly low frequency content. In this context the origin is typically in MOS or MOSFET interface states. Synonym of flicker noise. Consisting of one photodiode and one access MOSFET, the simplest passive pixel. Are pinned photodiode pixels (see 4T) organized in groups of typically 2 or 4, whereby the floating diffusion is common. E.g. a group of 4 pixels, having 4 transfer gates, and 1 reset, 1 source follower and 1 column switch, have 7/4= 1.75 transistors per pixel. Two 2T pixels have had some limited success in the past Hitachi’s 2T pixel is a variant of the passive 1T pixel, with two switc
