*2.118 Adesigner,wantingtoachieveastablegainof100 V/V at 5 MHz, considers her choice of amplifier topologies. Whatunity-gainfrequencywouldasingleoperationalamplifier require to satisfy her need? Unfortunately, the best available amplifier has an ft of 40 MHz. How many such amplifiers connected in a cascade of identical noninverting stages would she need to achieve her goal? What is the 3-dB frequency of each stage she can use? What is the overall 3-dB frequency?
