Hi all,

I have been searching for this document a long time, and the only source I found was to buy the seminar proceedings for $ 280.00 While I normally would not hesitate to purchase papers, this is a bit too steep for me. Anyone have a copy they are willing to share? Or any other paper describing the DXCCII?

"Ali Zeki, Ali Toker, "The Dual-X Current Conveyor (DXCCII): A new active device for tunable continuous-time filters", International Journal of Electronics, vol.89, no.12, pp.913-923, Dec 2002."

Thanks beforehand,

Jan Didden

Janneman,

Here is my guess, since I have not seen the paper.

I just googled the dxddcc. From an abstract, page 10 of:
http://inspec.iee.org/inspec/currentawareness/pdfs/products/samples/IEE_filter.pdf
"A new active circuit building block: dual-X differential difference current conveyor (DXDDCC)"

It is a differential difference current conveyor (DDCC),
with two x connections.

The web site:
http://web.bsu.edu/tti/3_4/3_4f.htm
shows the DDCC.

Thus the dxddcc seems to have three y inputs, two x connections and a z output.

My guess would be the x connections could be the same voltage or opposite of each other.
The z connection could be either the the sum or difference of the x connection currents.

That's my guess.

According to the title of the article, the device was invented by the authors, so it is not likely to appear in any previous publications (ie. not before 2002). Since it is an academic publication, it is obviously not secret work (and I know you were just joking about that Jan). Probably one can find at least brief descriptions of the device in later articles by the same or other authors, that is, provided it has been found useful.

Hi Tom,

I was aware of the first ref, in fact most of the innovations in analog current mode design nowadays seem to come from one or two universities in Turkey!

The second is quite usefull, I had seen references to the UCC they discuss but not seen the paper itself. Thanks for that, I will try to deduce the setup from that.

Yes, thanks. It'll turn up sooner of later anyway ;)
