Oscillator circuits

Oscillator circuits are electronic devices that generate continuous, repeating signals—usually in the form of electrical waves—without requiring an external input. They work by using components like resistors, capacitors, and amplifiers to create a feedback loop that sustains oscillations at a specific frequency. These circuits are fundamental in producing signals for radios, clocks, and communication systems, acting as internal “clocks” or signal sources. In essence, they convert energy into a stable, periodic waveform essential for guiding various electronic devices and systems.
