RF-powered Internet of Things (IoT) sensor duty cycles are limited due to low available energy at long range in the absence of a battery. Additionally, RF energy harvesters with high- $Q$ interfaces between the antenna and rectifier suffer from poor

IoT transceiver deployments are envisioned to have low power, low data-rate ($\sim$kb/s) wake-up receive (WuRX) and Mb/s primary receive (RX) modes for long battery lifetimes [1]. WuRX architectures based on energy-detection (ED) achieve ultra-low po

2017 IEEE Radio Frequency Integrated Circuits Symposium (RFIC).
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 sen
