| Oct 11, 2019 at 16:19 | comment | added | D.A.S. | No , R5 purpose in A is different than B . Are trying to make A perform like B? Then use cct B. | |
| Oct 11, 2019 at 14:50 | comment | added | mmyname | So is it a current limiter? how can I design its value? | |
| Oct 11, 2019 at 14:16 | comment | added | D.A.S. | In Amp A that would short out the signal with 100uF. What is your real issue? | |
| Oct 11, 2019 at 14:10 | comment | added | mmyname | The voltage divider R2, R3 provide the DC bias 2.5 V. What if I did not add R5 ? | |
