Wien Bridge Sine-Wave Generator Circuit Composed of F007

Published:2011/5/3 20:24:00 Author:Sue | Keyword: Wien Bridge Sine-Wave Generator Circuit Composed of F007

As seen in the figure is wien bridge sine-wave generating circuit. This circuit uses voltage stabilizing diode to stablize amplitude, and the oscillate frequency is 1kHz. If we replace the 1.5kΩ resistance with a coaxial duplex potentiometer, or change the capacitor value with a wave band switch, we can adjust the output frequency. The highest frequency of a circuit is decided by operational amplifier's frequency characteristic, while the low frequency terminal requires a larger resistance value, so the operational amplifier's input impedance should be as high as possible. In the voltage stabilizing diode branch, which is between the 680Ω and 3.9Ω resistance, there is a 30kΩ resistance to prevent the gain change from varying too quickly. If voltage stabilizing diode with soft breakdown characteristic is used, there will be less distortion, and the distortion rate can reach 0.5%.   (View)

Low-Cost Wien Oscillator Circuit Composed of F007

Published:2011/5/3 20:24:00 Author:Sue | Keyword: Low-Cost, Wien, Oscillator

As seen in the figure is the low-cost wien oscillator circuit. On one hand, it can solve the problem of using expensive inductance coil in ordinary oscillatory circuit, on the other hand it can avoid the problem of using duplex potentiometer to adjust frequency in ordinary wien bridge oscillator. Ituses onlyone potentiometer to adjust fequency, so the cost is low. Despite of the narrow range of adjusting frequency,it is still useful when the frequency range is not large, and this circuit has a good stability.   (View)
