摘要
为了解决物联网无线节点通信的功耗问题,设计了一种高能量效率和低功率消耗的唤醒接收机.该唤醒接收机基于唤醒机制有效地调度网络节点通信,并利用简单的包络检波架构进行频率变换,从而能够灵活地管理能量和降低功耗.该唤醒接收机基于65nm CMOS工艺进行仿真设计.仿真结果表明,当射频中心频率为780MHz和输入信号采用开关键控调制方式,该接收机可以实现输入匹配参数S11为-21dB,灵敏度在数据率1Mb/s下为-76dBm,并且在1.2V供电电压下,功耗消耗为76μW.
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 65 nm CMOS process technology, the wake-up receiver is designed and simulated. The results show that it can achieve Su of --21 dBm and a sensitivity of --75 dBm at a data rate of 1 Mb/s, when operating at the central frequency of 780MHz and input signal adopting an on-off keying （0OK） modulation, and the power consumption is 82 μW at 1.2 V voltage supply.
