Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

I HAVE NOT RELABELLED ANYTHING.  What is wrong with you?  What we've done is PHYSICALLY SWAPPED the SOURCE WITH THE GATE.  And what I've then done is relabelled the schematic accordingly. 

If it is not clear, I have been, and am referencing the apparatus (and how it was connected) in the video demonstration.

If you are now discussing a different circuit connection from the one used in the video demonstration, then I believe it would be prudent to advise the readership to that effect.

No.  I am not referring to anything other than the 'modified schematic' that I posted - here today.  I'll repost it for clarity.

I see you're getting angry there Poynty.  And I also see that you're missing this all by a mile.  Just look again at the positioning of the source and the gate.  And then consider what it sees when it sees a postive charge from the signal generating battery.  Just look at it upside down if you have to.

Here it is again.  And, with the exception of the bias of that zener - it's precisely how our circuit is designed - up to and including the position of the CSR.

Please then clarify for the readers; does your above diagram accurately depict the circuit connections for the apparatus in the video demonstration?

Yes.  With the exception of the position of the ground from the signal generator.  And there has to be a connection between those two (or more) MOSFETS that's omitted.  And - correctly - the zener at the drain on Q2 needs to be reversed biased.   Otherwise I think it's right.

ADDED.  And that we're using a functions generator - obviously.

At a point not too long ago, the attached was the circuit connections diagram for that video demonstration.

Clearly the diagram you are now presenting, is substantially different from the original in the video.

Could you please, for the benefit of the readership here, explain how the CSR has been relocated to an entirely different position? Also, PLEASE provide a complete schematic of the apparatus in the video demonstration, if the attached is not already one that is correct.

This is all not making much sense Rose, and I think you're losing not only readership here because of this, but losing everyone in general (including me), in terms of their understanding of what exactly you are trying to discuss here.
