As shown in the figure is a high quality low frequency signal generator circuit characteristic of well-performed fixed amplitude, large output power and little wave distortion. It is a kind of ideal low frequency signal source. In the figure, operational amplifiers A and its feedback network constitute a typical venturi oscillator, whose oscillation frequency is:f0 = 1/2π RCA2 . The output end is connected with complementary push-pull power amplifier OCL to improve the load capacity of the circuit. Operational amplifier A1 is connected into a negative half-wave amplifier, and composes a negative feedback fixed amplitude circuit with W1, R4, C1, and T1 ect.
