| Popis: |
A ultra-low power wake-up receiver based on a novel fast sampling method is presented. The innovative approach allows the scalability of current consumption versus data rate at a constant sensitivity, meeting both short reaction time and ultra-low power consumption requirements. The 868 MHz OOK receiver comprises an analogue superheterodyne front-end and two digital 31 bit correlating decoders. It is fabricated in a 130 nm CMOS technology. The current consumption of the prototype is 1.2 μA at 2.5 volts supply voltage and a reaction time of 484 ms. The receiver sensitivity is -83 dBm thus obtaining a line-of-sight distance of 1200 metres for an assumed transmit power of 10 mW. Compared to other sub-100 μW receivers, the sensitivity of the presented implementation is best. |
