In the figure is a stable-amplitude and low-distortion power signal generator of XG404C. The circuit is a good power signal source which consists of the audio power amplifier XG404. In the figure, C2, R1,C3 and R2 form a Wien-bridge frequency-selecting net, which decides the frequency of the sine wave. The leakage equivalent resistors of R3, R and FET pipe T1 determine the magnified times of the amplifier non-inverting input. When R=R1=R2 and C=C2=C3, the oscillating frequency of the circuit is f0=1/2πRC , according to the element value, the frequency is about 1kHz.
