A Highly Reconfigurable Bit-Level Duty-Cycled TRF Receiver Achieving −106-dBm Sensitivity and 33-nW Average Power Consumption

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- null null \mu \text{W}null null null average power consumption, improving sensitivity over other sub- null null \mu \text{W}null null null receivers. The receiver rejects interference using a compact RF MEMS filter and a fully automatic gain and offset...
