The voltage gain of an amplifier is described by A(s) = 2π ×1010s /(s+2000π)(s+2π ×106) (a) What are the mid-band gain and upper- and lower-cutoff frequencies of this amplifier? (b) If this amplifier is used in a feedback amplifier with a closed-loop gain of 100, what are the upper-and lower-cutoff frequencies of the closed-loop amplifier? (c) Repeat for a closed-loop gain of 40.
