A Near-Zero Power Reconfigurable and Robust Multiband RF Wake-Up Receiver Achieving −108dBm Sensitivity Operating from −40° C to 70° C

This work presents the first sub-microwatt wakeup receiver (WuRx) with better than −100dBm RF sensitivity operating over a wide range of temperatures and showing excellent resilience in the face of adversarial RF jamming. This device operates in multiple relevant RF bands spanning from 433MHz to 930MHz, with an ultra-compact form factor. At minimum power consumption, the device can continually operate for decades when powered from a coin-cell battery. Compared to prior art, this device achieves an excellent combination of high sensitivity and low power, without the use of custom MEMs devices, decreasing cost and integration complexity while improving temperature robustness and frequency tunability. The device operates from −40°C to 70°C with better than −100dBm sensitivity, and shows significant improvement in figure of merit compared to non-robust state-of-the-art.
