hello

how to make the flipped voltage follower with nmos input gain close to 1?

the opposite one, from the picture gives me 1V/V gain and with nmos input gives me about 0.7V/V I want to build complementary buffer with that.

regards

hi, thanks for the paper


unfortunately i can't find the mistake, the buffer's gain is still far from 1.

maybe it's not suitable for low 1.3V supplies? the fact is it attenuates input voltage.

did someone design this buffer?

regards
