I mean to ground these two drains point through a resistor instead of directly.

My simulator does not like that... what is the reason?😕

Other question: can I improve the switching from class A to AB upon high power demand?

Thanks

Does your simulator like no grounding of that point.
I mean, why is this grounding necessary?

you are correct, my simulator does not like it without grounding.
The grounding was for my simulator to be happy... 🙄 thus you bring a good question🙂 I guess a similar question could apply to the jfet cascode reference point...

Thanks
