(Essentials of Transistor Oscillator)Fig-1 shows the block diagram of an oscillator.


Essentials of Transistor Oscillator




Its essential components are :





(i) Tank circuit





It consists of inductance coil (L) connected in parallel with capacitor (C).





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.





Changes it into a.c. power for supplying to the tank circuit.





The oscillations occurring in the tank circuit are apply to the input of the transistor amplifier.





Because of the amplifying properties of the transistor,





we get increased output of these oscillations.





Fig-1




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.
