This circuit is a phase-shift oscillator. The set of three capacitors and two resistors form a filter that shifts their input by 180 degrees at the oscillation frequency. The output of this filter goes into an inverting amplifier, and the output of this amplifier goes back into the filter, providing positive feedback at the oscillation frequency. -- Credits: Mr. Paul Falstad.

|Very good. If there is another simulator to produce three output frequency 1, 5, 10khz by one amplifier in the time. I mean by switches.|

The simulator allows to modify the circuit design.
You can design and simulate it by yourself. Just right click on the simulator, you will get lot of options.
Have a nice day!

|I just want to ask how to modify your circuit? for example i want to change the frequency output?
what will be the computation for the R=?
and the capacitor=?

|How would you design an RC phase shift oscillator which oscillates at 100kHz frequency?|
