Key Concepts
This section describes the basic operating principles for all oscillators and explains the operation of feedback oscillators.
It also analyzes the operation of a basic RC sinusoidal feedback oscillator and demonstrates simple oscillator applications.
- Oscillator Basics
- Feedback Oscillator
- RC Op-amp Oscillator (Phase-shift oscillator)
- Triangular-Wave Generator (Relaxation Oscillator)
- Square-Wave Oscillators
Important Pointers
- Feedback Oscillator: returns a portion of the output back to the input to control oscillation.
- Relaxation Oscillator: uses an R-C timing network to control oscillation.
