Rc oscillator

Wien Bridge Sine Wave Oscillator. 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. "Initial conditions" is set to "User defined". "Initial voltage" (IC) for Cfsp is enabled and set to 3.333 V. Values in the millivolts and lower range result to very small output amplitudes. "Manual time step" is enabled and "Time step" is set to the default value of 1e-5 s to make the graph smoother. Increasing the feedback resistance increases the distortion. It results to oscillation that grows in amplitude and stabilizes when the voltage swing limit of the op-amp is reached. Lower "Initial voltage" (IC) for Cfsp results to longer stabilization time.
