应用于物联网的纳瓦级唤醒接收机芯片
Nanowatt wake-up receiver for IoT applications
摘要
Abstract
To address the power waste problems of wireless receiver module in the Internet of Things,a nanowatt wake-up receiver is de-signed and implemented.The wake-up receiver"wakes up"the main receiver after receiving the wake-up signal.The wake-up receiver system includes matching network,passive envelope detection,baseband amplifier,comparator,correlator and digital comparator.The proposed passive envelope detection replaces the traditional active detection circuit,significantly lowering the system power consumption,while providing 23.6 dB passive gain with the front-end passive matching network.The information is modulated by on-off keying(OOK).The wake up receiver is designed based on 65 nm CMOS technology.Under the carrier frequency of 433 MHz,data rate of 100 bps and code length of 8 bit OOK signal,the sensitivity of the wake up receiver can reach-72 dBm.The power consumption of the ana-log part is 21.9 nW,and the power consumption of the digital part is 93.8 nW.关键词
