Yes, it's correct! There is only one last think I don't understand with bootstrap and Miller effect.
From what I've seen, this circuits input resistance is much more reliant on input signal frequency. I mean increasing frequency decrease input resistance much faster. Why?
Hello,
I have problem with input resistance of emitter follower.
But first quick check:
**broken link removed**
If I'm correct, equation for input resistance will be:
Rin = RB || Rin'
where:
RB = R2 || R3
Rin' ≈ hie + (hfe + 1)R5
Ok, that was quite easy. But the real problem I have with this...
