Wein Bridge Oscillator Using Op Amp Circuit Diagram. An oscillator is a circuit that produces periodic electric signals such as sine wave or square wave. The circuit diagram of wien bridge oscillator is shown in the figure below.
The circuit schematic diagram and the design formula september 15 2008 circuitguy the excellent high input impedance high slew rate and high voltage qualities of ca3140 op amp make it suitable for wien bridge sine wave oscillator. The application of oscillator includes sine wave generator local oscillator for synchronous receivers etc. The wien bridge oscillator op amp is used as the oscillator circuit and it is working like a non inverting amplifier.
Since a wien bridge oscillator requires an ic in order to work the lm741 is our ic of choice in this circuit.
Basically it is just an amplifier with one positive feedback the series and parallel rc network and one negative feedback the 1 8k resistor the potentiometer and the incandescent bulb.
