IEEE Open Journal of the Solid-State Circuits Society (OJ-SSCS): Wake-up receivers (WuRXs) offer energy-efficient means to enable asynchronous wake-up of higher power/higher performance radios without needing frequent (often energy-expensive) synchronization. Since WuRXs are typically on for a long time, keeping their power consumption very low is critical to minimizing the total energy draw. However, this is difficult while maintaining e.g. good sensitivity, interference resiliency, and robustness. This recent article from the Open Journal of the Solid-State Circuits Society reviews the main challenges facing WuRXs, outlines the most popular WuRX architectures, and details essential design techniques and tradeoffs toward enabling utility in emerging applications.
