Very interesting. In Russia, there were once circuits of radio receivers based on logic elements. Your Tektronix MDO is my dream.. Cool content. Continue to please us with your videos! ;)

The topology looks like a class B but it's actually more like a coupled class A pair or a class A with active load. You can see that each MOS is doing active gain in a common emitter configuration. A classical class B would work as source followers without voltage gain. We could measure the thd of one stage !
I read it was necessary to use unbuffered gates. But trying with the HC04 using a low impedance output to increase gain margin seems to work fine as I demonstrated !

this is pretty much the only video in regard to this topic. Congratulations. Cheers
Thank you! Share the channel with your friends to help me grow it

Nice ! Do you have some schematics?
The MDO is a nice equipment, but sometimes I prefer the Agilent dsox.
Thank you for your support!

What are capacitor values at input and output?
They need to be a short (low reactance) for the frequency of operation. I think I used 10nF..
Just curious, could this be used as an audio input buffer to drive an ADC?
It can work! But it will be far from good design!
Isn't this just basically a Class-B amplifier? Curious about the amount of crossover distortion.

Muito bom esse vídeo :)
Thanks friend!
Yo should have used the 4069UB instead and it will be more clear....
