I am a noob with analog electronics, so pardon me for any mistakes. I recently started with Op-Amp and currently working on a project whereI am using Op-Amp in integrator mode to convert square wave to triangle wave and then fro there again an integrator to convert that triangle wave to sine wave.
I tried the circuit with single power supply that is +5V and ground, but was not able to make to work. So is it mandatory to use a dual power supply like +5V and -5V for an Op-amp to work as integrator? Because all the circuits I referred to were using a dual mode power supply.
Additional details: The Op-Amp is LM358 and the square wave is from an arduino board +5V and 0V obviously. The duty cycle of the wave is fixed at 50% and the freq. is controllable from 100Hz to 100KHz. I tested the whole set-up with 1KHz freq using my DSO.
