on which the different modules are displayed.
The image core is a pixel array of 1280 * 1024 pixels each of 14
*14 μm2 in size. The readout is from bottom left to top right. To
obtain a frame rate of 450 frames/sec for this resolution, 16
output amplifiers each capable of driving an output capacitance
of 10 pF at 40 MHz are placed on the image sensor.
The column readout amplifiers bring the pixel data to the output
amplifiers. The logic and the x- and y addressing controls the
image sensor so that progressive scan and windowing is
possible. Extra pixel array drivers are foreseen at the top of the
image sensor to control the global pixel array signals.
Pixel Architecture
The active pixels allow synchronous shutter, i.e., all pixels are
illuminated during the same integration time, starting from the
same moment in time. After a certain integration time, the pixels
are readout sequentially. Readout and integration are in parallel,
which means that when the image sensor is readout, the
integration time for the next frame is ongoing. This feature
requires a memory element inside the pixel, which affects the
maximum fill factor. A schematic representation of the pixel is
given in
