Designing High-Performance Amplifiers (Analog Circuit Design Series: Volume 3) — Recommend this title to your library

Circuit speed is basic to analog circuit performance, and designers seek to extend bandwidth “from dc to daylight.” Yet speed is not the only performance criterion. In audio, bandwidth that is much beyond human hearing degrades performance due to increased noise; the important measure of performance is fidelity, the precise reproduction of the input waveform. In this looser sense, precision means ideal analog waveform processing.
