Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFColpitts oscillator:
- The Colpitts oscillator consists of one inductor and one split capacitor in the tank circuit.
- A capacitor with a center tap is used in the feedback system of the Colpitts oscillator
- It is used for the generation of sinusoidal output signals with very high frequencies
