提出了一种综合的剩余放大器功率估计方法。使用这种方法的功率效率的定义，随后被用来分析最近发表的，高效的剩余放大器。设计参数的确定有关键影响的功率效率，并根据功率效率的设计选择进行了讨论。结果表明，最省电的剩余放大器的拓扑结构共享相同的核心电路，不同的主要是如何从输入驱动这个核心电路。最后，概述了这些拓扑结构，功率效率排名。
A comprehensive method for power estimation of residue amplifiers is presented. Using this method a definition of power efficiency is given, which subsequently is used to analyze recently published, highly efficient residue amplifiers. Design parameters are identified which have a key influence on the power efficiency, and design choices based on power efficiency are discussed. It is shown that the most power-efficient residue amplifier topologies share the same core circuit and differ primarily in how this core circuit is driven from the input. Finally, an overview is given of these topologies, ranked on power efficiency.
