An Oscillator-Based Wake-Up Receiver for Wireless Sensor Networks
The Internet of Things (IoT) concept is mainly enabled by wireless sensor networks (WSNs), which are continuously gaining attention, due to their multidisciplinary applications. To enhance the WSNs energy efficiency, different solutions have been proposed. One of them is the integration of wakeup receivers (WuRxs), which activate the sensor nodes through an identity-based approach. In this work a low power oscillator-based WuRx architecture is presented, and verified by simulations in TSMC-180nm CMOS process. The WuRx sequentially verifies if the received signal resembles the wake-up call (WuC) one by means of oscillators, counters and logic gates. It consumes $16.1\mu \mathbf{W}$ when detecting a 1.6ms WuC signal, and 1.2nW in idle mode.
