本文提出了一种唤醒接收器（WuRX）的设计，通过多方面的设计，与现有技术相比，既提高了灵敏度，又降低了功耗，该设计具有具有大无源电压增益的片外阻抗变换网络、具有高输入阻抗以促进大无源电压增益的有源包络检波器、低功耗精密比较器和低泄漏数字基带相关器。 OOK 调制 WuRX 采用动态阈值电压 MOSFET (DTMOS) 器件，采用 180 nm 绝缘体上硅 CMOS 工艺实现，工作频率为 113.5 MHz，灵敏度为 -69 dBm，而 0.4 V 电源功耗仅为 4.5 nW。
This paper presents the design of a wake-up receiver (WuRX) that both improves sensitivity and reduces power over prior art through a multi-faceted design featuring an off-chip impedance transformation network with large passive voltage gain, an active envelope detector with high input impedance to facilitate large passive voltage gain, a low-power precision comparator, and a low-leakage digital baseband correlator. Implemented in a 180-nm silicon on insulator CMOS process using dynamic threshold-voltage MOSFET (DTMOS) devices, the OOK-modulated WuRX operates at 113.5 MHz and achieves a sensitivity of -69 dBm, while consuming just 4.5 nW from a 0.4-V supply.
