i've searched some articles and learned that if you feed a square wave in an integrator you'll be able to produce a triangle wave. also you need to have to match the frequency of the input to the RC of the integrator.

my op-amp multivibrator indeed produces a square wave which has the same frequency as the RC of the integrator and yet i'm still recieving a square wave at the output of the integrator. pls help

 

You don't have power connected on U5.

its still not producing a triangle when connected

RC time constant is too short.

 

RC time constant is too short.

i increased the capacitance value(from 1nF to 3nF), and i can now get a triangle waveform, but the problem is that the waveform shifted upwards is that normal?
