Abstract

IoT transceiver deployments are envisioned to have low power, low data-rate ($\sim$kb/s) wake-up receive (WuRX) and Mb/s primary receive (RX) modes for long battery lifetimes [1]. WuRX architectures based on energy-detection (ED) achieve ultra-low power (ULP) C0nsumpti0n but have poor sensitivities ($\sim-$60 to -40dBm) for 26dB Signal-to-Interference Ratio (SIR) at 2MHz offset for4Mb/s OPSK interferer) and high-linearity in the primary RX (0.75dBm IP1dB) and (iii)high-sensitivity in both wake-up (-86dBm) and primary RX (3.8dB NF) modes through noise cancelling, while consuming 171uW in wake-up RX mode (including RF L0) and 440uWin primary RX mode.

21.4 0.75 ~ 1ghz无源宽带降噪171µW唤醒RX和440µW主RX FE， -86dBm/10kb/s灵敏度，35dB SIR和3.8dB RX NF

物联网收发器部署被设想为具有低功耗，低数据速率($\sim$kb/s)唤醒接收(WuRX)和Mb/s主接收(RX)模式，以延长电池寿命[1]。基于能量检测(ED)的WuRX架构实现了超低功耗(ULP)消耗，但在2MHz偏置4mb /s OPSK干扰下，对于26dB信噪比(SIR)具有较差的灵敏度($\sim-$60至- 40dbm)，并且在主RX (0.75dBm IP1dB)中具有高线性度;(iii)通过降噪在唤醒(- 86dbm)和主RX (3.8dB NF)模式中具有高灵敏度，而在唤醒RX模式(包括RF L0)和440uWin主RX模式中消耗171w。
