Rosemary Ainslie Circuit Demonstration, June 1 2013

In all fairness though, there must be some "negative" gate drive signal happening or the oscillations would not occur. The circuit clips the negative gate voltage at around -4 volts, IIRC, so you will never see a gate signal more negative than that, no matter how negative the FG's offset is cranked. But you knew this already.
So, since the Fig3 scopeshot shows around +12 volts at the peaks, the question we now ask is whether or not the FG that Ainslie used, is capable of making a +12 volt square wave if the offset knob is cranked all the way to the negative stop as is claimed. I don't think it is, but maybe. Certainly my Interstate can but I don't know about the Instek model Ainslie used.

But this would not resolve the Fig3 discrepancy, it only would reveal Yet Another discrepancy between what the scopeshot shows and the claims being made.

I hope you're not despairing for a replication of her scopeshot ..... I still can't find my coloured pencil set.

can you post the schematic here? I saw one in pesn but seems like nothing special.
A typical topology in power electronics that would reduce the Rds_on of the circuit.

Well, Mark.... just by doing nothing you are already in her sights.

Notice again the continuing lies and distortions and veiled threats coming from Ainslie. Also note that, for the first time in ages, she does not refer to me as "Bryan Little".

Also note that she attempts to deflect the issue. The issue is NOT whether I can make those scopeshot traces, because I MOST CERTAINLY CAN, simply by removing the Q1 mosfet from its socket. The issue IS, and will remain, that AINSLIE cannot make those traces under the conditions described in the manuscripts. Nobody can.

PROVE ME WRONG, you bloviating fool Ainslie. It would take you five minutes to do, but YOU CANNOT. You know perfectly well that your mosfet was blown.... I HAVE YOUR BLOG And FORUM POSTS ADMITTING THAT YOU BLOW MOSFETS WITH YOUR APPARATUS.
