用于物联网通信的低功耗唤醒接收机设计
Design of the low power wake-up receiver for internet of things communication
摘要
Abstract
A wake-up receiver with high energy efficiency and low power consumption is proposed for solving the power consuming problems of wireless nodes communication in the Internet of Things.The proposed wake-up receiver based on the wake-up mechanism can effectively schedule the network nodes communication, and use the simple envelope detection structure to achieve frequency down-conversion, which can flexibly manage energy and reduce power consumption.Based on UMC 65nm CMOS process technology, the wake-up receiver is designed and simulated.The results show that it can achieve S11 of-21dBm and a sensitivity of-75dBm at a data rate of 1Mb/s, when operating at the central frequency of 780MHz and input signal adopting an on-off keying (OOK) modulation, and the power consumption is 82μW at 1.2V voltage supply.关键词
