Circuit Simulator - Sawtooth Wave Generator

@Author.

I tried this circuit. Its not producing waveform. I tried with different values.

Thanks for the diagram. I drew up the circuit in Orcad Capture and was able to run it fine. I changed the capacitor to a smaller value to increase the frequency. I am trying to design a circuit that produces a sawtooth at about 110-120 Hz to mimic the fundamental frequency of a male speaker.
I used Capture to generate a Fourier transform of the signal, and thought that the energy drops off pretty quick for what I want. I'm messing with different component values to try to decrease the dropoff.
I changed the 5k for a 2k, and the upper 40k for 80k, resulting in an even steeper slope in the fast component of the waveform. The Fourier transform resulted in an even bigger drop between the fundamental and the second harmonic, but the amplitude at higher frequencies seems to persist.

Can somebody explain what types of AO are in the circuit and what power supply it needs?

Multivibrator needs no input.

What are the applications of the saw-tooth generator?

No voltage source input why?

Lots of people seem to be having problems with this circuit. I assure you that with sensible op amps and component values it works perfectly. For those that have tried and failed are you using a split supply for your op amp (ie +/- Vcc)? If you are using a single supply then the grounded inputs to the op amp need to be connected to a mid supply voltage, easily established by two 10K resistors.

Use an op amp with rail to rail output for maximum ramp voltage. For those that have asked for how the circuit works the RH op amp is an integrator. The LH op amp is a Schmitt trigger with hysteresis from the positive feed back to reset the integrator. The circuit is readily adjusted to alter both the ramp frequency, the ramp amplitude, and the ramp average voltage. Note that as drawn the 5K resistor and the diode connected to the 40K resistor are not actually required.

How saw tooth wave works?

I try it. And the circuit doesn't work. My output just jump on maximum voltage level.

I tried with different voltage dividers answer still doesn't work.

What is the application of sawtooth?
