Thumbs up Push-Pull Output Stage MOSFET Tester

hi, not much to comment really
Whether you use it for SPICE MODEL testing or
Build Something like it for your REAL MOSFET tests.

Voltage GATE-SOURCE ( VGS ) for a specific DRAIN CURRENT ( ID )
And for both the NMOS and the PMOS transistor.

Perfect for see approximately what values your transistors will have
at an idle Current in your PUSH-PULL Output Stage.

This setup used 5 Ampere and 20 Volt DRAIN-SOURCE.
So this is something what these EXICON Lateral
will have for VGS at 100 Watt per devices!

Hi Lineup,

honestly I don't see any benefit in a push-pull VGS-tester compared to the usual source-follower, would you enlighten me?

What's the use of the nameless basis-collector caps?

Have fun, Hannes

of course,
the same can be done with bipolar BJT
for get the HFE gain of output complementary Pairs
and V b-e drop at different OOUTPUT currents

i have a couple of those bipolar circuits, too
to examine spice models when i design my amplifier ideas
