| Jul 16, 2016 at 16:49 | comment | added | Ashik Anuvar | @Andyaka the circuit is operating at low supply voltage, so maximum positive swing is only around 0.43V and the gain is 48dB. I have updated the FFT with more cycles. please do check | |
| Jul 16, 2016 at 15:59 | comment | added | Andy aka | Try using a much finer resolution FFT over many cycles of the input signal. Also, why are you injecting a signal that produces an output that is -20 dBV? | |

| Jul 16, 2016 at 15:36 | comment | added | user16324 | You have bigger problems with that FFT ... possibly a DC component that is being mistaken as an impulse? That is hiding the other harmonics. You could calculate the 2nd harmonic distortion though. | |
