>> For Common Emitter configuration, output characteristic are :
>> DC Load line is plotted on output characteristic, graphically to calculate the DC values of and
>> DC Load line obtained through KVL in output loop.
>> For a given value of Base current, the point of intersection of output characteristic and DC load line is called an operating point or Quiescent point.
>> Operating point gives the DC values of and . [ This method is applied in industry to calculate the accurate value of and ]
>> For a given value of and . Thus it represents all collector current levels and corresponding collector-emitter voltages that can exist in the circuit.
SELECTION OF OPERATING POINT
Case 1 : Operating point near Saturation region
Case 2 : Operating point near cutoff region
Case 3 : Operating point at the center of Load line / Active region
>> Output signal is perfect sinusoidal means no distortions are present in the output.
