摘要：

In this paper, an ultra-low power address detector is designed and implemented within a Radio Frequency (RF) wake-up receiver (WuRx) operating at Wi-Fi 802.11b/g bands. The address detector aims to wake-up a sensor from sleep mode to active mode. The WuRx receives a wake-up call (WuC) as a pulse with a specific width that determines the address of the targeted sensor. Once this pulsed WuC is received by the antenna front-end, it is driven into a rectifier circuit that is lodged within the WuRx. The signal is then forwarded into a designed address detector that identifies the address of the sensor based on the width of the received pulse. The designed system relies on ultra-low power components for a selective RF wake-up of a targeted sensor without using a microcontroller or an active processor.
