提出了一种唤醒接收器 (WuRX)，只需 6.1 nW 的功率即可实现 -80.5 dBm 的灵敏度。高灵敏度是通过具有高输入阻抗 ( $> 750~\text {k}{\Omega }\;{\|}{ pF) 的无源伪巴伦包络检波器 (ED) 实现的，它可实现 30.6dB 无源电压增益变压器，同时提供差分输出，并且与给定输入电容的传统单端输入无源 ED 相比，将转换增益提高 ${2}{\times }$。 WuRX 采用 180 nm CMOS 工艺实现，并采用 0.4V 电源供电。
A wake-up receiver (WuRX) that achieves −80.5-dBm sensitivity with only 6.1 nW of power is presented. High sensitivity is achieved via a passive pseudo-balun envelope detector (ED) with a high input impedance ( $> 750~\text {k}{\Omega }\;{\|}{ pF) that enables a 30.6-dB passive voltage gain transformer while providing differential output and improving the conversion gain by ${2}{\times }$ compared to a conventional single-ended input passive ED for a given input capacitance. The WuRX is implemented in a 180-nm CMOS process and operates from a 0.4-V supply.
