Wein Bridge Oscillator Circuit Diagram Using Op Amp. The op amp in the circuit is not ideal but a virtual model. Although the circuit does not have a power supply the positive voltage swing vomp and negative voltage swing vomn are parameters that make the output bounded so the circuit oscillates as expected.
This oscillator is a low frequency oscillator. Although the circuit does not have a power supply the positive voltage swing vomp and negative voltage swing vomn are parameters that make the output bounded so the circuit oscillates as expected. If you want to know all the pinout of the lm741 op amp what each pin is and what each pin does see lm741 op amp pinout.
The resistances r1 and rf forms the part of the feedback path which determines or facilitates to adjust the amplifier gain.
This bridge circuit can be used as feedback network for an oscillator provided that the phase shift through the amplifier is zero. Since a wien bridge oscillator requires an ic in order to work the lm741 is our ic of choice in this circuit. Figure 1 schematic diagram of wien bridge oscillator circuit. Although the circuit does not have a power supply the positive voltage swing vomp and negative voltage swing vomn are parameters that make the output bounded so the circuit oscillates as expected.
