Very Clearly explained and thank you for giving the use case @ Burra Dhanunjaya.

However, there will be difference in application and performance of CB and CC configurations most of the people they don't consider this.

CB: To isolate output signal, impedence matching.

CC:providing high input impedence, low output impedence, high Bandwidth.

Very clearly explained thanks @Ajay.

Y-> gama B-> beta < ---> alpha

Y = B+1 = 1/1- < = 1/(1-0.99) = 100.

Why do we change modes from CC to CB or vice versa?

What is the practical application of changing transistor modes?
