Ultra-low power consumption awakening receiver of wireless node of internet of things and short-distance wireless internet

Abstract

The invention relates to an ultra-low power consumption awakening receiver of a wireless node of the internet of things and the short-distance wireless internet. The ultra-low power consumption awakening receiver comprises a radio-frequency signal matching network, a front end amplifier, an envelope detector, a limiting amplifier, a first comparator, an integrator, a second comparator and an edge trigger. The radio-frequency signal matching network is used for achieving impedance matching of the front end amplifier and an antenna. The front end amplifier is used for amplifying signals. The envelope detector is used for detecting amplitude envelope of the signals and converting the signals to differential pulse signals. The limiting amplifier is used for amplifying the differential pulse signals. The first comparator is used for converting the input differential pulse signals to single-ended pulse signals. The integrator is used for integrating the single-ended pulse signals. The second comparator is used for comparing the integrated voltage signals and reference voltage signals. The edge trigger is used for awakening an anode chip to enter the working mode according to the comparing result of the second comparator. The ultra-low power consumption awakening receiver is used for externally remotely controlling the wireless network node to lead the wireless network node to accord with network scheduling or used for controlling the working state of the short-distance wireless internet and information transmission nodes.

Description

technical field [0001] The invention relates to the technical field of low power consumption of the wireless communication of the Internet of Things, in particular to an ultra-low power consumption wake-up receiver used for the wireless nodes of the Internet of Things and short-distance wireless interconnection. Background technique [0002] IoT technology will be widely used in all aspects of economic life and national security in the foreseeable future, and will increasingly affect economic development (such as in finance, logistics, commerce, etc.) and social life and national security (such as disasters) monitoring, early warning, etc.). Compared with the convenient wireless interconnection technology, the power consumption of the node circuit and the whole system will become more and more obvious constraints for its wide application. For a large number of scattered IoT nodes, using power line power supply is obviously an unrealistic and inappropriate solution. However...
