CMOSIS Global Shutter Pixels

ElectroIQ: CMOSIS publishes a fairly detailed article "Global shutter image sensors" by Guy Meynants. The article compares few types of GS pixels, dividing them into charge domain and voltage domain families:

    Hi,
    A tiny typo: It's Guy Meynants.

    thanks for your blog :-)

    FIGURE 2. (b) 7-transistor charge domain global shutter pixel
    Is it really charge domain?

      Thats a typo, he writes voltage domain in the text.
      However, I do not agree with the statement that 5T global shutter pixels dont allow CDS. That can be done by storing the digital values of the reset levels in a peripheral memory...
