Abstract :
An envelope detector-based wake-up receiver front-end is presented. A double-sampling technique is implemented to suppress the 1/f noise and DC offset, resulting in a lower output noise level and therefore a better SNR for a given input level. The receiver consumes 51 μW and occupies 0.36 mm2 in 90 nm CMOS. For 10 kb/s 00K reception it achieves -69 dBm and -80 dBm sensitivity at 2.4 GHz and 915 MHz respectively.
