Abstract :
An ultra-low power 2.4 GHz RF Wakeup Receiver is designed for wireless sensor networks nodes. The receiver demodulates On-Off Keying at 100 kbps. A 120 nm CMOS chip includes the analog front-end and consumes only 7.5 mu W from a single 1.5 V supply. The digital signal processing is implemented in an FPGA. The results of measures and simulations are evaluated for the use of this receiver in wireless sensor networks.
