宽带通信接收机的能量消耗高度依赖于A/D转换级的参数化。节能接收机的设计需要一个最佳的参数化。本文从信息论的角度研究了当前A/D转换器的功耗问题，并对最优参数化进行了研究。结果表明，大采样率和非常低的量化分辨率通常是最节能的。
The energy consumption of wideband communications receivers depends highly on the parametrization of the A/D conversion stage. The design of energy-efficient receivers requires an optimal parametrization. This paper investigates the power dissipation of state-of-the-art A/D converters and studies the optimal parametrization from an information theoretic perspective. The results show that a large sampling rate and very low quantization resolution will usually be most energy-efficient.
