  1. Who is this guy? His 4T design is really original with a resistive load inside. :)

  4. Thanks for catching the error. I'm making these videos in my spare time as a fun side project and so there's no QA. I've never designed an image sensor. I'm mostly a happy end user.

    I'll re-make the relevant videos to clearly show there is not a resistive load per pixel for the source follower. I'll do that this week and maybe tonight.

    If you find any other errors I'm happy to hear about them.

    Here, I organize my videos according to playlists:

  5. I re-made the 2 of the 3 videos affected and added a annotation to the third. Here are links to the re-edited videos:

    http://youtu.be/6NtEHYX6Nlc

    I left the original videos as visible if one has the link. That way traffic from this blog doesn't reach a dead link.

    But, I added a lengthy annotation to the beginning of each noting the error and giving direction to the re-edited videos.

    Thanks.

  6. Blake,

    Thank you. I've changed the links in the post to point to the new versions.
