Data Sheet

50µm-pitch Wide Aperture Spectroscopic Photodiode Arrays

4.0 Self-Scanning Circuit

Figure 5 shows a simplified electrically equivalent circuit diagram of the photodiode array. An MOS read switch connects every

photodiode in the array to a common output video line. Incident photons generate electron charge that is collected on each imaging

photodiode while the switch is open. The shift register is activated by the start pulse. A pulse propagates through each shift register

stage and activates the MOS read switches sequentially. As the shift register sequentially closes each read switch, the negative stored

charge, which is proportional in amount to the light exposure, from the corresponding photodiode, is readout onto the video line, QOUT.

Typically, an external charge-integrating amplifier senses the negative output charge on the video line from each photodiode pixel. The

shift register continues scanning the photodiodes in sequence, until the last shift register stage is reach, at which time the fourth and

last dummy pixel is read out and end-of-scan (EOS) output is held high for one clock cycle. The next start pulse can then restart the

shift register.
