Two FET amplifiers are operated in cascade. If the gain of the amplifiers is equal and the total overall gain is 25, the gain of each amplifier is
A)12.5.
B)5.
C)2.
D)7.25.

Question

Quizplus · Accepted Answer

The total gain of cascaded amplifiers is the product of their individual gains. If both have equal gain (let's call it G), then the total gain is G^2 = 25. Solving for G gives G = 5.
