Hello,

Sehr schön. Looks very good for starting point. A little remark: I think the M6-M7-R1 complex will need to be replaced to a constant-gm reference (otherwise the bias current will be highly supply-dependent). Also, "syntax error" near M1-M5 (floating gate).

I would recommend that we move the repo under libresilicon (it is easier for others (newcomers) to find there, there is already a sort of chaos from repos distributed under multiple users). I will clone a "work copy" for myself and have the changes pulled when ready (as done while working on pearlriver, to reduce merge conflicts).

Regrds,
Ferenc

Hello List!

Today on our weekly Mumble session we talked about the "triple-5" once
more. So I got itchy fingers and set up my personal repository for that
on github (https://github.com/chipforge/CMOS-555).

Well, no repository without content - please check the README file and
see the Schematic I already draw now. For everybody which is lazy to
install Lepton-EDA (as describted in the README) I attached a fency
screenshot.

Please check the Schematic, based on the Wikimedia SVG drawing, for
mistakes I did. All dimensions for the transistors (Width, Length) and
the restistors (Resistance) are still just generic. This task I suppose
will do someone of you which is more an analog guy than me :-)

BTW, Tatzelbrumm and Ference, do you like to clone the repository and
we're merging each other? Or, otherwise I can shift the repository to
the github.com/libresilicon group and we are working there. What do you
prefer?

Best Regards,
Hagen.

P.S.: Other versions of the CMOS "555" circuit I saw, will follow soon
as schematics - one e.g. even has on BJT.
