The amplifier shown in Fig. P5.11 is formed by cascading two first-order feedback systems. Both amplifiers have the same transfer function, , given by (5.22) with and . The overall cascade has a dc gain of 100. Estimate the overall bandwidth? How does this compare with the overall 3-dB bandwidth that would be obtained by implementing the entire gain of 100 in a single feedback amplifier constructed from the same amplifier, (but obviously a different value of )?
