For each amplifier shown below determine the closed-loop gain and bandwidth. Each op-amp has an open-loop gain of 125dB, unity-gain bandwidth of 2.8MHz , and is internally compensated so that the output rolls off at -20dB/decade. (15 points) Hint: Use the fact that the gain-bandwidth product is a constant
