    The operational amplifier (op-amp) of any type has some performance limitations imposed by the supply voltage rails. Namely, the voltage signal amplitude at the input or the output of the operational amplifier needs to fit within the bounds of the power supply range. These limitations are denoted in question 5 by the Rail-Rail property of the two op-amps. If the Rail-Rail property of the ...

    Solution Summary

    The output response of the op-amp is explained in terms of the Rail-Rail properties by using the voltage follower configuration.
