- An amplifier can be converted into an oscillator by doing some change in the amplifier circuit as:
- Connect the output of the amplifier to the input by a positive feedback circuit.
- The phase-shifted the output by 180° and feed this phase shift output to the input via a feedback circuit.
- An arrangement of the RC tuned circuit is connected as a load to the amplifier.
- Oscillator circuit block diagram.
