I have 4 op-amps in cascade with a gain of 10 each to give a total gain of 10000. I noticed the circuit produces a DC offset which then gets amplified causing the amplified signal to clip asymmetrically.
I know op-amps have an offset pin but I have never used it before and I am looking for the simplest solution. I thought I might simply add a capacitor after each op-amp but I don't know how large it should be or if it would help. The signal I am amplifying is 40 kHz.
What is my best option?
