The circuit is an ultra-low frequency oscillator consisting of precise clamper circuit, which is almost a standard non-steady multi-resonance oscillator. In the figure, A3 and A4 form a symmetric precise clamper amplitude-limited circuit, with the clamper technology, the expensive voltage steady diode of temperature compensation is not needed, the feature of the circuit is that the stabilization depends only on the stabilization of the power supply voltage, and just the single polarity voltage can fulfill the dual polarity clamping. The reference voltages V1 and V2 on A3 and A4 are supplied by the reference voltage source μA723.
