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.

Gives
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
