another small breakthrough on our NERD technology.

[Rosemary Ainslie]

Sorry Schubert,  I missed this. 

1) So I continue to pulse Q1 normally.

It works - experimentally - when we apply a continual negative pulse at Q1.  NO Q2 REQUIRED. 

3) The input signal is an AC type or a pulsed DC.4) I have tested my sim with a AC type because with the pulsed DC it return me a bug (Q2 is the cause of the bug of course).

Maybe just try it with a continual negative at the gate of Q1?  It works experimentally.  Just a thought.

Thanks again Schubert.

Removed Q2 and negative pulsed Q1: as expected it does nothing...

Don't know in real world mode what happen. Here I can't say something since I haven't tested (and I have over other work currently cannot test... )


SRM.

See, the thing is SRB,

You and I (and most everyone else) knows that Q1 can not be active with a negative voltage applied to its Gate, but Rosemary thinks it is. She is STUCK on this error in her thinking and knowledge. How could anyone take her seriously about her claim when she clearly does not understand how the circuit works?

[Rosemary Ainslie]

Thanks Schubert,

Well.  It goes to show that something's missing from the software in those sims.  It works fine in the real world.  LOL.  I'll ask someone to do that 'click download' thing and take a look at in the morning.

All very interesting.  I seem to remember that Poynty can get this to oscillate on his Pspice software.  Not sure though.   I know he gets it to work with the Q1- Q2 array number.  And we've got lots of sims on that config. 

In any event.  Many thanks Schubert.

Kindest regards,
Rosie

Poynty Point - can I impose on you to just hold back on your propagandising for the moment and show Schubert your sims.  Not your results.  Just your oscillation.

Then you can get back to these rather tedious references to my poor abilities.  It seems to give you some kind of relief - and it does me no harm - so I've no objection.

Kindest as ever,
Rosie Posie.
