Abstract

This paper presents a fully integrated wake-up receiver (WuRx) with direct active RF detection. The RF front-end features a high-sensitivity RF detector embedded with input matching network, obviating the need of RF amplification and LO generation for frequency downconversion. This complete receiver contains an RF detector, IF amplifiers, and a continuous-time ΣΔ ADC to provide inherent anti-alias filtering, which simplifies the overall design in 0.18-μm CMOS process. It achieves a sensitivity of -65 dBm for data rate of 100 kbps, operating in 2.4 GHz ISM band with only 10 μW. By adjusting the input matching, it can also operate for 5.8 GHz band, providing -50 dBm sensitivity without additional power consumption.
