FC amp, there is any method to reduce H3?
What do you think about this input stage?
It is my new amplifier and this stage will be coupled with classA_25W/classB_100W triple darlington output stage with 5 peers of Onsemy 0302/0281 power BJTs The NFB gain will not be more than 40dB. What can I improve in this stage to reduce H3? Mihai |

Why don't you try AD797 topology, folded cascode + diamond buffer = one gain stage as well. See my findings below for inspiration...
