Stabilisation and Stability factor.

Stabilisation and Stability factor
Due to the variations of transistor parameters with temperature, the collector current of a transistor changes rapidly and hence the operating point also changes. Thus the biasing circuit, should be so designed that with a change of Ico, the corresponding change in Ic should be as small as possible so that the operating point should remain almost fixed. This is called stabilisation.
The process of making operating point independent of temperature changes or variations in transistor parameters is called stabilisation.
