Is it possible to buffer a sine wave using inverters alone or with some kind of feedback?
I've been browsing google for minimalistic (I'm in 3.3-12 V domain) sine wave buffers and this thought stuck in my mind.
The idea was there, because I came upon High Speed Digital CMOS Input Buffer Design by Krishna Duvvada, and I already asked a question with this in reference but of a different kind, so I don't think I'm breaking any rules with this one.
I realized, a bit later, that in that master thesis, that's actually not how you would wire the output of the first stage, the rail to rail input stage. Do you agree? So it's some kind of inverters structure basically.
I don't have enough knowledge to contribute my thoughts, and my thoughts are currently very tangled, hence the question.
