Consider two alternatives for designing an amplifier having a dc gain of 100. The first alternative is to use a single non-inverting stage, having a gain of 100.The second alternative is to cascade two non-inverting stages, each having a gain of 10. Op amps having a gain bandwidth product of 106 are to be used. Write an expression for the gain as a function of frequency for each alternative. Find the 3-dB bandwidth for each alternative.
