Q.	During high frequency applications of a B.J.T., which of the following three stages do not get affected by Miller’s approximation?
A.	c.e.
B.	c.b.
C.	c.c.
D.	follower
Answer» B. c.b.
Explanation: during the c.b. stage, the capacitance between the base and the collector doesn’t suffer from miller approximation since the input is applied to the emitter of the b.j.t. there are no capacitors connected between two nodes having a constant gain. hence the c.b. stage doesn’t get affected by miller approximation.
