Assignment

1. Construct a Colpitt’s Oscillator having the frequency 2000 Hz and amplitude 6 V (using the power source 12 V).
2. Calculate the frequency of the Colpitt’s Oscillator if L = 5µH and C1 = C2 = 5nF.
3. Design a Colpitt’s Oscillator having frequency 1000 kHz and amplitude 5 V (Power source 12 V).
4. In a Colpitt's oscillator, the value of the capacitors in the tuned circuit is 50 pF and 100 pF, and the sections of coil have inductances 12μH. Find the frequency of oscillations and feedback factor β.
5. A Colpitt’s oscillator circuit has C1 = C2 = 100μF. The frequency of oscillations required is 50 kHz. Calculate the value of the inductance required.
