| Popis: | A 2.4 GHz 365nW wake-up receiver (WuRX) with RF envelope detection using rectifier-antenna co-design for passive voltage gain and RF filtering is presented. The RF frequency-tunable WuRX uses a programmable 32-bit OOK wake-up signature, achieving sensitivity of −61.5dBm for 2.5 kb/s without any off-chip matching components between IC and antenna. RF filtering in the high-Q rectifier-antenna interface results in 10−3 BER even with interferer-to-carrier ratio of 19.1 dB for CW blocker at 3MHz offset. The 65-nm CMOS WuRX IC occupies 1.1mm2, while the WuRX (including antenna) occupies 1.875cm2. |
