In this paper, a fully integrated photo sensor in standard CMOS technology is reported, which enables light spectral analysis in the visible light range without additional optical components like color filters or gratings. The proposed sensor structure provides a continuously tunable spectral responsivity based on lateral carrier diffusion effects in combination with tunable field electrodes for defined...
An integrated color detector is presented, which is implemented in a standard 130 nm CMOS technology without process modification or additional optical components like color filters. The proposed structure consists of vertically and laterally arranged photodiodes, providing color separation based on lateral carrier diffusion and wavelength-dependent absorption-depth. Three independent detector output...
