Figure 3: architecture of the LUPA sensor
Figure 3 shows a schematic representation of the image sensor 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 40MHz 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.
