Phase Shifter Circuit. In phase shift circuits with lumped parameters the phase shift is due to the effects of the reactive components such as capacitors and induction coils. The result is an all pass filter that has input to output quadrature i e quarter wavelength or 90 phase shift at ω 1 rc i e f 1 2πrc.

The feedback network shifts the phase of the amplifier output by 180 degrees at the oscillation frequency to give positive feedback. Intuitively the phase shifter uses a first order low pass filter to create a phase shift and negative feedback to compensate for non unity gain. Phase shift oscillators are often used at audio frequency a.
A phase shift oscillator is a linear electronic oscillator circuit that produces a sine wave output.
