Q. Discuss the essentials of an oscillator?
The essential components of an oscillator are
(i) Tank Circuit: It consists of inductance coil(L) connected in parallel with capacitor (C0. the frequency of oscillations in the circuit depends upon the values of inductance of the coil and capacitance of the capacitor.
(ii) Transistor Amplifier: The transistor amplifier receives d. c. power from the battery and changes it into a.c. power for supplying to the tank circuit. The oscillations occurring in the tank circuit are applied to the input of the transistor amplifier. Because of the amplifying properties of the transistor, we get increased output of these oscillations. This amplified output of oscillations is due to the d.c. power supplied by the battery. The output of the transistor can be supplied to the tank circuit to meet the losses.
(iii) Feedback circuit: The feedback circuit supplies a part of collector energy to the tank circuit in correct phase to aid the oscillations i.e. it provides positive feedback.
