As filter operating frequencies approach higher and higher frequencies, their response begins to change in unpredictable ways, presenting the designer with an increasingly difficult design problem. Many of these effects are related to the slew rate limitation of the amplifier and begin to manifest themselves decades in frequency below the unity gain bandwidth. A 1 GHz amplifier may be limited to a few hundred kilohertz when used in a filter design. This chapter presents these limitations and shows actual examples of how successful ...
