ams Dragster – High-Speed Line Scan Image Sensors

Dragster is a platform of digital line-scan sensors. The sensor family is made using three types of basic elements: a single line element from 2K to 8K pixel resolution (7 μm pixel size and pitch), a dual line element from 2K to 8K pixel resolution (7 μm pixel size and pitch) and a single line element from 4K to 16K pixel resolution (3.5 μm pixel size and pitch). The chip versions with dual line are optionally available with Bayer Pattern RGB filters placed on the sensors.
The sensor features a low noise pixel with true CDS and global shutter for interleaved readout and integration operation. Start and end of integration, as well as optional start of readout, are started upon individual external trigger events.
The readout is made by digital taps organized in odd/even order for each 2K segment. For each line segment, 2K (7 μm pixel) or 4K (3.5 μm pixel), all pixels are read out. For sensor versions with 3.5 μm pixel pitch, two 2K segment readout circuits are placed on each side of the pixel line, to lead to a basic segment of 4K pixels, where even pixels are read out over the bottom readout and odd pixels are read out over the top readout.
