Consequently, quartz crystal oscillator circuits are more top-quality when compared to other resonators like LC circuits, tuning forks. Generally in Microprocessors and Micro controllers we have been using an 8MHz crystal oscillator. The inverter provides 180o of stage change and the crystal capacitor network the additional 180o essential for oscillation. https://manueleimor.blogdemls.com/34863111/timing-components-for-consumer-electronics-for-dummies
