Hi everyone!

I am looking for a circuit which can transform from rectangular pulse into triangle pulse. Does any one help me.
Thank a lot

PS: The circuit must operate at 40KHz

 

You can always use an integrator to do that - http://www.play-hookey.com/analog/triangle_waveform_generator.html

 

Hi beenthere!
Thank for your help. Can you show me the value of components and type of integrator in proteus. There are a lot of integrators and I can't find the appropriate integrator.
