ams Technology Guide
Global shutter CMOS image sensor pixels are needed to capture the scene for all pixels at the same moment in time. ams developed a unique global shutter CMOS pixel that combines true correlated double sampling with an excellent shutter efficiency. Each global shutter pixel uses two memory elements, which sample the signal and its reference value.
ams developed a new CMOS image sensor pixels that allows readout of a photodiode with a wide dynamic range, which maintains a linear response to light. After exposure, the photodiode is read out via two transfer gates to two sense nodes. Two signals are then read from each pixel.
ams developed a backside illuminated CMOS imagers for extensions of the wavelength band beyond the visible range. Devices have been developed for detecting light outside of the visible band, in the near UV (200-400 nm) or extreme UV band (15-50 mm).
