Problem 8 Operational amplifiers are often compensated for an acceptably transient response or gain peaking when connected in a standard feedback configuration such as shown in part (a) below. The consumer often uses the amplifier in other configurations. Shown below are four different amplifier structures. Assume that in all cases the resistors are chosen so that the dc gain is 100. Assume the op amp has been designed so that it has a dc gain of 100,000 and a pole at 10 rad/sec. Analytically compare the 3dB bandwidth and the amplifier poles of the following four circuits assuming the same op amp is used in all four cases. Comment on the relative performance of the four different finite gain amplifiers. R2 RA RA R1 R1 R1 VOUT VOUT VIN VIN (a) (b) R2 R2 R1 w R ww VOUT Vout VIN VIN (c) ) (d)
