该论文提出了一种用于无线个人/体域网的2.4GHz接收机，采用滑动中频相位数字转换器架构，实现了1.2nJ/b的能效。主要解决了传统能量检测或超再生接收机在拥挤的2.4GHz ISM频段易受干扰的问题，同时提高了能效。
4GHz RX for short-range wireless personal and body-area networks. In such applications, the RF transceiver consumes up to 90% of the total battery energy in a remote sensor node. In order to extend the operation lifetime, it is a primary design goal for such transceivers to improve the energy efficiency, expressed as power consumption/data-rate, to below 1nJ/bit. Although energy-detection or superregenerative ASK RXs [1] are very efficient, they are vulnerable to interference and this leads to a poor quality of the wireless link in a crowded 2.4GHz ISM band. On the other hand, FSK/PSK-type modulations are popular in the target applications because of their power-efficient hardware and higher immunity to interference. They are also widely adopted in many short-range wireless
