Distinguish is as follows:
| Ring Oscillator | LC Oscillator |
|---|---|
Circuit diagram fig. 3 stage ring oscillator |
Circuit Diagram fig. LC tunned oscillator |
| Jitter is more in ring oscillator as compared to LC oscillator | Jitter is less as compared to ring oscillator |
| Ring oscillator has worst phase noise | Better phase noise performance |
| Requires smaller layout area compared to LC oscillator | Layout area is more compared to ring oscillator |
| It has larger tunning range | It has smaller tunning range |
| Applications: High speed clock synthesizer, VCO, PLL | Applications: Wireless reciever for cellular use, VCO, PLL |
