Outline
Wake-up receiver（WuRX）is a critical module for achieving low-power wireless sensor networks.Classical wake-up receivers which adopts envelope detection（ED）as the first stage，suffer from low sensitivity.To address this issue，the traditional single-ended ED in WuRX is extended to a single-ended-to-pseudo-differential topology，thereby improving the conversion gain and output signal-to-noise ratio of the ED.Additionally，the baseband circuit adopts a low-power fully differential structure，which enhances its ability to suppress common-mode noise，and ultimately improves the sensitivity of the WuRX.Furthermore，this design employs a collaborative approach for the internal current source and clock generation circuit，which reduces current consumption through shared paths.The chip is designed using a 65nm complementary metal-oxide-semiconductor（CMOS）process，with a carrier frequency of 109MHz and a data rate of 33.3bps.Simulation results demonstrate that the proposed WuRX achieves a sensitivity of-80dBm under conditions of a false alarm rate below 1 per hour，and a miss detection rate below 0.1%；moreover，the WuRX operates with an overall power consumption of only 5.9nW at a supply voltage of 0.4V.Compared to classical WuRX designs，this work achieves higher sensitivity while maintaining low power consumption.
