Q.

If the load resistance of a C.E. stage increases by a factor of 2, what happens to the high frequency response?

A. the 3 db roll off occurs faster
B. the 3 db roll off occurs later
C. the input pole shifts towards origin
D. the input pole becomes infinite
Answer» A. the 3 db roll off occurs faster
Explanation: if the load resistance increases by a factor of 2, the output pole decreases since it’s inversely proportional to the load resistance. hence the c.e. stage experiences a faster roll off due to the pole.
