Help on Looser-Take-All / Winner-Take-All circuit

Good morning,
a friend of mine have inserted this post on a Forum I created on my site
[url]www.etantonio.it/en[/url] , this is the question :

"Someone knows something about LTA/WTA circuits?
I mean the best approach to the problem,
the best topology and all that can be usefull
to design an accurate and high-speed LTA?"

I don't know the answer, if you know it please post it just following this link:
