The Collector feedback helps to evade __________

The Collector feedback helps to evade __________ Correct Answer Thermal Runaway

The increase in the Collector current is primarily due to ICO. A sudden increase in ICO can increase the Collector current and this will increase the temperature of the device. This is called thermal runaway and due to the high current gain of the transistor, the transistor can get destroyed due to thermal runaway. The Collector feedback configuration helps to evade this phenomenon.
