Triangular Wave Generator for a fixed frequency

Emmanuel Mendez Alicea

Hello,

I'm trying to build a triangular wave generator for a fixed frequency of 10 kHz. I'm trying to create a simple circuit. I've seen some simple examples that uses a multivibrator that generates a square waves and then is pass through a integrator to generate the triangular wave. I also seen VCO that generates triangular waves, but all the circuits I've tried to simulate just doesn't work. It is a little frustrating.

To be more specific, I need a triangular wave generator that goes from 0V to 5V with a fixed frequency of 10kHz. That's basically all. 

Any help or tip will be appreciated.

Thanks!

    Hi Emmanuel,

    The reference design TIPD108 describes the design of an analog PWM generator.  A requirement of the PWM generator design is to produce an accurate triangle wave which will likely fit well in your application.

    Thank you so much Collins!! This design helped a lot. Finally I could make the generator and I'm also making a PWM with a triangular wave so this design you share with me helped me to understand better.

    Again, thanks for sharing this guide!
