A Design of 5.8 GHz Ultralow-Power Wake-up Receiver: 14 kHz On Off Keying for DSRC Application

This paper proposes an ultralow-power wake-up receiver(WuRx) for DSRC (Dedicated Short Range Communication) transceiver application. The proposed WuRx receives 5.8 GHz signal and demodulates it into a 14 kHz on off keyed signal. The proposed WuRx is fabricated in 0.13- μm CMOS technology with the size of 0.26 mm

. At the operating frequency of 5.8 GHz, WuR achieves a -62 dBm sensitivity while consuming 3.3 μW from a 0.9 V supply voltage.
