Q. What is the need for bias stabilization in BJT?
BJT or bi-polar junction transistor is a three terminal, two junction semiconductor device and the conduction is due to the majority and minority carriers, hence it is a bi-polar device. BJT amplifies the electrical signal as they transferred from the input to the output. A few advantages of the BJTS are given below
· Low current requirement
· Small size
· Less weight
· Long operating the shelf life
· Rugged in nature
Slow-rise, fast-decay
