Spurious Charge

When using CCDs for applications where binning of more than 4 pixels is required, care has to be taken to design the CCD driver circuit to avoid the generation of spurious charge. During the design phase and, most of all, during the final camera test and calibration procedure, precaution is taken to deliver all cameras tuned to generate no additional spurious charge.

How is spurious charge generated ?

How to reduce spurious charge ?
There are three methods used in the our cameras to reduce the shot noise produced by spurious charge to negligible levels.
