Physical description of a CCD
CCD main functions
By schematizing, four fundamental moments can be identified:
Typical sructure of a three phase CCD
The figure on the right shows the scheme of a three phase CCD. In this case the pixel is made by 3 MOS elements. Along the vertical columns the separation is obtained with the stop channels (dashed lines).
In this scheme 4 fundamental areas can be identified:
