I needed a circuit with op-amps for saw tooth waveform generation, I came through the following circuit and modified it according to my requirements.The circuit worked fine in simulation, but practically when I mounted It gave a triangular instead of saw tooth waveform ,and frequency was a little less
I tried playing with resistance R1 that could make it more saw tooth insead of triangular by reducing it, and with resistance R2 increasing it. But reducing it resulted in distorted waveform and increasing R1 increased the frequency and made it more triangular whereas. Changing R2 didn't had much significant of an effect.What could be the problem?
