Study and Design of a WLAN WSN Wake-Up Receiver

Research on wake-up receivers is gaining momentum due to the growing demand for this compact yet crucial component in advanced technological systems that rely on radio-based communication. Wake-up receivers play a key role in minimizing the activity of the main radio, thereby significantly reducing energy consumption, and extending the overall system lifetime. This paper provides an overview of the design considerations and challenges associated with wake-up receivers, along with a comparison of several existing architectures. Additionally, a Wireless Local Area Network (WLAN) wake-up receiver is validated using Advanced Design System (ADS) software. A performance comparison between Amplitude Modulation (AM) and Differential Quadrature Phase Shift Keying (DQPSK) modulation schemes is also presented.
