As shown in the figure is a low frequency multi waveform generator circuit. This circuit can output two kinds of waveform simultaneously: triangle wave and square wave. In the circuit, the first stage is a standard integrator; the second stage is a phase inverter whose gain is 1; the third stage is a hysteretic comparator. When the third stage does not have a diode, output of the circuit is positive, output of the integrator is negative inclined wave, which will turn into positive inclined wave after being inverted and will then be added to the comparator.
