Testing the TK Tar Baby

[MileHigh]

Groundloop:

There is still a problem somewhere, perhaps one of the MOSFETs is damaged?  The maximum gate-to-source leakage current for Q2 is 100 nanoamperes.  It's possible that Q1 has a drain-to-source leakage current problem.  The leakage current should be less than 500 microamperes.  Have you checked the direction of the current flow you are measuring?  You need to measure the bias leakage current for each MOSFET separately to understand what is going on.

When you play with a circuit and you make a measurement that is way off you want to investigate in more detail.  There is clearly a problem somewhere for the positive bias input mode.

We, the guys, would like to make it clear to everyone that we do not support Rosemary's claim or work in any way whatsoever and we dislike the way she often uses the term guys when making her posts.

As most people are aware, Rosemary has no support anywhere. No one ever supports her claims anymore.
So, stop using the term guys to refer to your audience.

Hello The.  That's an unusual name you've chosen.  Or is your name 'guys'?  Equally unusual.  But don't please confuse my use of this term with you, or anything associated with you - for that matter.  I am only speaking directly to the 'men' who either read here or are members of this forum.  And it is in that 'not feminine' sense of the word that I use that term - or better put - term of address.  It's a preference of mine.  I've always found men to be reasonable, fair, courteous, kindly, upright - really excellent people.  I'm rather fond of them.  Definitely, in my view, the 'better' half of the two genders. So.  it's an unfortunate truth that there are so few such who post on TK's thread.  In fact I can barely count them on one hand.  Actually I can barely even count them of four fingers.  But math has never been my strong point.

And you're right.  I do NOT apparently have that much support from the contributors to this thread.  Thank you God.  I suspect that they don't like to engage with all you women.  Which is MORE than understandable.  The more so when you lot are all so excessively petty.  Men somehow rise above all that.  Actually so do most women.  You lot are a rare breed of animal.  And I most certainly have support.  Lots of it.  Again. Thank you God.

Rosemary:

And as for this?  I am under NO obligation to answer any question that you put to me.  EVER. If you want co-operation TK - then apologise PROFUSELY for your legal transgressions.  And then follow this up with an attitude of professional respect.  LOL.  Then I'll give you LOT's of attention. 

You are so full of shit.  You are fully engaged and "defending" your proposition but when an experiment is done that clearly shows that current can flow right through the signal and ground connections of the function generator output, then you play your morally bankrupt "I am under no obligation" card.  I will remind you again that that is exactly what was happening with your setup when you did your testing last year.  I will also remind you that you and the entire NERD team were unaware that this was happening.  Talk about hapless blind ignorance.  The La Mancha Prize indeed.

Meanwhile, the whole energy/power/joules/watts debate shows just how skewed your understanding is and how belligerent you can be.  We will have to try to work around your "word salad" descriptions of these terms in an effort to get you to do your dim bulb testing.

MileHigh,

No, there is not any problem. Both my MOSFETS is brand new and OK.

I'm measuring a bias current to be 0,09 Ampere at 13,75 Volt when simulating the FG positive pulse.
The input voltage was 24 Volt current was 1,74 ampere. I use a 10 Ohm RLOAD. My Rds(on) is 1,6 Ohm. My RSHUNT is 0,25 Ohm.
I have not checked the direction of the current flow I'm measuring. I have no more time today to test.

Hi Poynty.  I've answered you in my edited post.  But just as a guide.  Watts are determined OVER time - where WORK is determined as a PRODUCT of time.

We've already discussed this.  Wiki therefore 'errors' - certainly on this point.

Rosemary,

Wiki is in agreement with the highly-esteemed "Hyperphysics" website as to what the "W" represents in that equation:
