Watch for Grey in Analog Science Fiction and Fact, the upcoming May or June issue.
He's too humble to tell you about it himself.

Michel,

Maybe you could tell us which issue of Electronics World the article will be in?
A folded cascode models as a single stage and adding a follower you have a two stage amplifier, close to a straight wire with gain, I suppose.
Nelson Pass, I believe, has used this approach in some of his designs.

Cheers,
Jam

Michel,

Just trying to get you to give up more information on the amplifier. You certainly have our attention.

Jam

I would also like to know if high feedback with resultant low distortion is your prime criteria for the design (straight wire with gain)?

I cannot disagree with you there. You seem to share the same views, as I do, on amp design.
I shall be waiting at the edge of my seat ........

Thanks,

Jam

i'd agree... mind you i've probably started @ least one that had less content ..... i get Electronics World each month so i'm itching to see your design. I probably wont use it but it'd be nice to see a little 'proof of concept' info...

Guys,

Let us not be too hasty to judge Michel. If he does not deliver, we can stone him later.

Michel,

Any chance of posting a conceptual (block diagram) of the schematic?

Default X?

This is interesting, however -- is this not exactly what the NP X input stage does?

http://www.passlabs.com/pdf/susy.pdf (or better still original patent at http://www.delphion.com/cgi-bin/view...=pdf&MODE=fstv)

I am not quite sure what a transimpedance stage is. Perhaps a short explanation on this might be in order since my Horrowitz and Hill is not avaible for now.

Petter
