[Paper] A 1/1.7-inch 20Mpixel Back-Illuminated Stacked CMOS Image Sensor with Multi-Functional Modes

Abstract

We have developed a 1/1.7-inch 20Mpixel back-illuminated stacked CMOS image sensor with multi-functional modes which are parallel multiple sampling, the two simultaneous output streams and data compression. This sensor has achieved a RMS random noise of 1.3e- with the parallel multiple sampling and the two simultaneous output streams of 4Mpixel for a movie mode and 16Mpixel for a still mode with a 2.3Gb/s/lane high-speed interface. Moreover, the high speed output mode of 16Mpixel at 120fps with a low image degradation compression. The stacked structure realizes on an analog implementation of the double column parallel ADCs.
