Abstract :
This paper presents an ultra-low-power 2-step wake-up receiver for the IEEE 802.15.4g. The receiver is composed of an ultra-low-power energy-detection receiver (EDRX) and an address-detection FSK receiver (ADRX). The ADRX is activated only when the EDRX detects a wakeup packet which minimizes power consumption. Fabricated in a 65 nm CMOS process, the receiver achieves an excellent receiver sensitivity of -87 dBm while consuming only 45.5 μW average power.
