By means of inductive coupling between L and L’, a suitable part of the output energy is brought back in phase and given to the tank for sustain the oscillations. The frequency of oscillations is Transistor as a switch: The circuit diagram is as shown below. The transistor as a switch operates either in cut-off region or in saturation region. P. S.: Draw transfer characteristics with this explanation from NCERT book. SAMPLE PROBLEMS FROM CBSE PAPERS (with solution). *** *** Solution: Dynamic output resistance
