I'm currently working on an op-amp circuit.
According to my calculations, the circuit I built should give me a gain around 1000 (30dB). However, it seems that the input voltage is dropping a lot when I check the op amp's output.
I've tried the 741 and the LM358N and none worked for me. I have also tried changing the resistors values but I don't see a considerable change. What am I doing wrong?
Here are the schematics:
Thanks in advance!
