Triangle wave generator

  1. Jan 12, 2006 #1
    I've attached a general schematic of triple wave generator with op-amp so i need to know the concept of genrating such waveform or maybe tutorial website, and any comment will be appreciated!

    It's an amplifying buffer for the input square wave, followed by the integrator. When you integrate a square wave, you get a triangle wave. The zener and other diode are used to set the amplitude of the square wave, and thus the amplitude of the tri wave.

    Electronic engineer: Any time we feed a capacitor with a current source the capacitor develops a linear ramp voltage across it. Since the capacitor in your schematic is the ONLY component in the feedback path there will be a constant current through it if the inverting and non-inverting inputs are to remain the same voltage. Of course there is a bit more to it since we are not figuring input offset voltages, the offset due to open loop gain and things of this nature.
