No matter what frequency, there are 360 degrees that can be associated with it (the phase). Here's an equation to summarize: V(t) = A sin ([w*t] + p) A is amplitude w = frequency p = phase shift
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.
basicaly the two inductors work as an autotransformer,providing a phase shift of 180 degree
A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output.
An analog phase shifter provides a phase shift with a varying control voltage. A digital phase shifter switches among phase states to provide discrete phase shifts. the more bits there are, the smaller the quantization/digitization error. For example, 1 bit phase shifter provides a phase shift of 0 and 180°, or 0 and 90°. 2 bit phase shifter provides a phase shift of 0, 90°, 180° and 270°. 3 bit phase shifter provides a phase shift of 0, 45°, 90°, 135°, 180°, 225°, 270°, 315°, 360°.
For a sine wave with maximum amplitude at time zero, there is no phase shift. The wave starts at its peak at time zero, and therefore, its phase angle is zero.

In a Michelson interferometer, phase modulation causes the interference fringes to shift along the detector. This shift changes the relative path length of the interfering beams, causing variations in the interference pattern amplitude. By analyzing these variations in intensity, the phase modulation can be detected as changes in the interferometer's output signal.
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.
