Definition and explanation of Stabilization and Need of Stabilization
Stabilization When the temperature changes or the transistor is replaced the operating point also changes. However for faithful amplification, the operating point must be remains fixed. This necessity to make the operating point independent of these variations. The process of making operating point independent of temperature changes or variations in transistor parameters is known as stabilization. Thus for maintaining the operating point independent of these variations, the following techniques are used. They are 1. Stabilization technique 2. Compensation technique Need of Stabilization The following are the factors that effect the stability of the operating point. 1. Temperature dependence of I C 2. Change of V BE and β due to replacement of transistor 3. Thermal runway 1. ...
