摘要

Power consumption is among the most important system-design parameters for designers choosing high-speed data converters. Power dissipation is critical whether in portable designs requiring longer battery life or for small products that dissipate less thermal energy. System designers traditionally power the data converter from a low-noise linear regulator, such as a low-dropout regulator, rather than a switching regulator because they worry that switching noise will feed into the output spectrum of the converter and significantly degrade ac performance.
