It is required to design an amplifier to have a nominal closed-loop gain of 10 using a battery operatedamplifier whose gain reduces to half its normal full-battery value over the life of the battery.

If only2% drop in closed loop gain is desired, what nominal open-loop amplifier gain must be used in thedesign? (The change in A is large, it is inaccurate to use differentials)

What value of B should bechosen?If component value variation in the B network may produce as much as ±1% variation in B, to whatvalue must A be raised to ensure the required minimum gain?
