CMOSIS Technology Guide
Global shutter CMOS image sensor pixels are needed to capture the scene for all pixels at the same moment in time. CMOSIS 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.
CMOSIS 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.
CMOSIS 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).

VGA high speed global shutter image sensor
The CMV300 is a high speed CMOS image sensor with 640 by 480 pixels (1/3" optical format) developed for machine vision applications.The image array consists of 7.4μm x 7.4μm pipelined global shutter pixels allowing exposure during read out and CDS operation. The user can choose between four digital LVDS serial outputs of 12 bits each, or one 10-bit parallel CMOS output. The image sensor integrates a programmable gain amplifier and offset regulation. Each LVDS channel runs at 480 Mbps maximum resultsing in 480 fps maximum at full resolution. Higher frame rates can be achieved in row-windowing or row-subsampling mode. All modes are programmable using the SPI interface. All internal exposure triggers, read-out timings and high speed clocks are generated by a programmable on-board sequencer and PLL. External triggering and exposure programming is also possible. Extended optical dynamic range can be achieved by multiple integrated high dynamic range modes.
2MP high speed global shutter image sensor
The CMV2000 is a high sensitivity, pipelined global shutter CMOS image sensor with 2048 x 1088 pixel resolution capable of HD format. Pipelining allows exposure during read out. The state-of-the-art pixel architecture offers true correlated double sampling (CDS) reducing the fixed pattern noise and dark noise significantly. The imager integrates 16 LVDS channels each running at 480 Mbps resulting in a 340 fps frame rate at full resolution at 10 bit per pixel. Driving and read-out are programmed over a serial peripheral interface. An internal timing generator produces the signals needed for read-out and exposure control of the image sensor. External exposure triggering remains possible. A 12 bit per pixel mode is available at reduced frame rate.
12MP high speed global shutter image sensor
The CMV12000 is a high sensitivity pipelined global shutter CMOS image sensor with a resolution of 4096 x 3072 pixels (super HD format). Pipelining means that exposure during read out is possible. The state-of-the-art pixel design makes true correlated double sampling (CDS) possible which reduces the fixed pattern noise and dark noise significantly. The imager integrates 64 LVDS channels each running at 300Mbps resulting in a 150fps frame rate at full resolution (10 bits per pixel). Driving and read-out programming can be set over a serial peripheral interface. An internal timing generator produces the signals needed for read-out and exposure of the image sensor while external exposure triggering remains possible.
