Im trying to simulate an differentiator Op-Amp using a single supply and the LM324 opamp. I built the differentiator circuit using a voltage divider and the LM3234 opamp.
The input wave is a Sinusodial wave, but the output wave is a square wave, but its suppose to be a phas shifted amplified sinusodial wave. I can get the amplification, but my output wave is not a sin wave.
What am I doing wrong, and how can i fix this?
Here is the Schematic of the circuit:
Here is a screenshot of the output:
Heres an example of what the output should be:
(the sin wave is the input, while the square wave is the output wave, but the output should be an out of phase amplified sin wave))
Best Answer
Your gain is too high, your output is clipping. At 60 Hz, the 1 uF (C1) will dominate and have an impedance of about 2.6k.
You either need to input a smaller signal, or lower the value of R2.
Edit: Or reduce C1 as Brian Drummond suggested.
