The phase-shift oscillator gets its name from the phase-shift network used in its design, which introduces a phase shift in the feedback path of the circuit. This phase shift is necessary for maintaining oscillations in the circuit.
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output.

There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
In an RC phase shift oscillator, one emitter follower stage is typically used to provide the required phase shift. In a Wien bridge oscillator, two emitter followers are used to achieve the required feedback and oscillation.

In order for an oscillator to be stable, its total phase shift must be 180 degrees. The most common design of an RC phase shift oscillator is three identical RC stages in series, which means that each stage contributes 60 degrees. For more information, please see the Related Link below.
