Sorry, you need a Java-enabled browser to see the simulation.  

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.
