How is positive feedback supplied in a Colpitts oscillator?
Through a tapped coil
Through link coupling
Through a capacitive divider✓الإجابة الصحيحة
Through a neutralizing capacitor
الشرح
The Colpitts oscillator takes its feedback from the junction of two capacitors connected in series across the tank. The ratio of that capacitive divider sets how much of the tank voltage is returned to the input to sustain oscillation.
