Phase distortion in operational amplifiers

Abstract: The stray capacities in the input and feedback paths of an operational amplifier, its finite bandwidth and d.c. gain effectively narrow the bandwidth of an amplifier causing amplitude and phase errors in the computer solutions. A given degree of accuracy consequently becomes more difficult to obtain with an amplifier when used in a high-speed repetitive computer than when used in a slower machine. In a high-speed computer, phase distortion is more serious than the amplitude distortion.
