RC Phase Shift Oscillator using Op-Amp A Phase Shift Oscillator is an electronic oscillator circuit which produces sine wave output. It can either be designed by using transistor or by using an Op-amp as inverting amplifier.

3 RC stages. 180° phase shift. One op-amp. That's all it takes to generate a clean sine wave from nothing. Here's how the RC Phase Shift Oscillator works — and how to build one yourself 👇
