A phase-shift oscillator circuit is a type of electronic oscillator circuit that generates an output signal with a 180-degree phase shift. It typically consists of an amplifier and a feedback network of resistors and capacitors arranged in a specific configuration to provide the necessary phase shift for oscillation to occur. The phase-shift oscillator works by creating a feedback loop where the output signal is fed back to the input of the amplifier with a phase shift of 180 degrees. This feedback causes the circuit to self-oscillate at a specific frequency determined by the values of the components in the feedback network. The operation of the phase-shift oscillator circuit relies on the proper alignment and values of the components to achieve the desired oscillation frequency and stability.
