Single-Slope ADC Book is Free to Download for a Limited Time

Now Publishers book "Welcome to the World of Single-Slope Column-Level Analog-to-Digital Converters for CMOS Image Sensors" by Albert Theuwissen and Guy Meynants is free to download, as a limited time promotion. The email I received from the Now publishers says:

"As this paper is one of the first publications in the new journal Foundations and Trends in Integrated Circuits and Systems, we are offering free access to all readers for a limited time.

The paper can be downloaded from the following link, would you perhaps be able to announce this on your blog, also stating that if readers want to be made aware of future publications they can sign up to the mailing list:

Access paper: now publishers - Welcome to the World of Single-Slope Column-Level Analog-to-Digital Converters for CMOS Image Sensors

Journal homepage, to sign up to the Alert List: now publishers - Foundations and Trends® in Integrated Circuits and Systems.


  1. Greatly appreciated!

  2. Tried to register at the publisher - required for the download. They said they would send a validation e-mail but never did. I think this is a device to get interested parties to contact them directly. Annoying amateur marketing behavior.

    1. It worked for me, I got the validation email. Have you checked your spam folder?

  3. Wow, thanks! I like Albert's way of writing: simple, straightfoward, and clear. I have his CCD book too. I wish other authors from other areas would emulate his style of writing.

    It is a joint effect, together with Guy !

    Joint efford of course, maybe also a bit a joint effect ;-)

  6. Back in 1999/2000 I invented both the multi-ramp single-slope and the multi-ramp multi-slope ADC architectures, and later published the inventions in a thesis in 2005 and a journal 2006. I expected to see reference to my work in this book, but instead Albert reference his own later work. I would like to see the book updated and include, e.g., a reference to
    L. Lindgren, "A new simultaneous multislope ADC architecture for array implementations", IEEE transactions on circuits and systems. 2, Analog and digital signal processing (Print), ISSN 1057-7130, E-ISSN 1558-125X, Vol. 53, no 9, p. 921-925, 2006.

    Leif, thanks for your reaction.
    The reference we used in our paper ("book") of M. Snoeij was published in Feb. 2007, a few months after your reference you mentioned (2006) in your comment. Please note that M. Snoeij presented his work already in 2005 at the International Image Sensor Workshop as well as at an smaller (local) conference intended for PhD students, and of which no papers or proceedings were published. Apparently M. Snoeij and you were working on the same problem at the same time and both of you came with a similar solution. That happens more often in this world.

  8. The work M. Snoeji presented 2005 seems to be just a single ramp solution. His first publication on multi ramp single slope and multi ramp multi slope seems to be from 2007. This is almost two years after my first official publication describing mrss and mrms, which was presented in my thesis from first half of 2005. I do not think we ever worked on this at the same time. My work was done 2000-2002 (maybe some stuff early 2003), but was not published until 2005 due to IVP Integrated Vision Products first wanted to keep it secret.

    Anyway, thanks for shareing the book for free.
