Abstract

This letter presents a reconfigurable wake-up receiver, which obtains -106-dBm sensitivity with power consumption as low as 33 nW. Bit-level duty cycling provides 68-dB RF gain at sub- \mu \text{W} average power consumption, improving sensitivity over other sub- \mu \text{W} receivers. The receiver rejects interference using a compact RF MEMS filter and a fully automatic gain and offset control loop. Digital tuning of dc power, latency, and sensitivity provides high levels of flexibility to enable a wide variety of applications, spanning latency from 240 ms to 5 s, dc power consumption from 288 nW to 33 nW, and sensitivity from -106 dBm to -103 dBm. Three example modes are presented to highlight the range of this tuning.
