Testing the TK Tar Baby

Now let me get this straight... you don't WATCH my videos... but you know precisely what is IN them.

I see.

And Poynty Point - sorry to quote myself here but I need to add this...

Poynty that diagram of yours is not right.  Your reference to that 'Q2' MOSFET shows the bias supply in series with the main supply.  Which is correct.  As is your Q1 MOSFET reference where you show the bias supply is in parallel to the main supply.  Here's where you 'error'.

. The body diode of your reference Q1 is NOT connected to the supply source or to the circuit's negative drain rail.
. It is ONLY connected to the terminal of the function generator's probe.
. It is floating - together with the your referenced Q1 Source.
. Therefore it CANNOT conduct current from the battery supply source -
. Even if that battery supply exceeded that diode's 'zener knee' voltage level

If you want to argue that the battery supply source can discharge current through your referenced Q1 you'll have to argue it against it's actual connections.

Regards,
Rosie

And may I add - IF that diode could conduct current from the battery supply while the bias supply is in parallel - then even more reason to suppose that it would do so while the bias supply were in series with the battery supply source.  In which case there would be a continual battery discharge and the MOSFETs would NOT switch.

The reason that you DON'T get your sim to oscillate under this configuration is possibly and PRECISELY because you show a continual connection of your referenced Q1 Source to the battery supply source's negative rail.  Under these circumstances there would be a continual discharge of the battery during both periods of each duty cycle.

No TK I DID WATCH YOUR VIDEOS.  I NO LONGER DO SO.

How vulgar and gross and grossly vulgar is THIS little video, Polly Parrot Ains-lie? Little Miss Pickle Measurer?

Ainslie said, stopping her ears with her fingers and squeezing her little eyes tightly shut:

What you are trying to do is to get me to believe that a function generator is able to pass current from a battery supply source via its terminal to its probe. Since I KNOW that is is impossible I'm afraid I'm not receptive to you trying to teach me or anyone else.  So NO.  I spare me your 'lessons'.

And TK replied, shaking his pickle....er... camera at her:

Facepalm. She has no clue what we have been talking about at all.
