An FSK and OOK Compatible RF Demodulator for Wake Up Receivers
AbstractThis work proposes a novel demodulation circuit to address the implementation of Wake-Up Receivers (Wu-Rx) in Wireless Sensor Nodes (WSN). This RF demodulator, namely Modulated Oscillator for envelOpe Detection (MOOD), is compatible with both FSK and OOK/ASK modulation schemes. The system embeds an LC oscillator, an envelope detector and a base-band amplifier. To optimize the trade-off between RF performances and power consumption, the cross-coupled based oscillator is biased in moderate inversion region. The proof of concept is implemented in a 65 nm CMOS technology and is intended for the 2.4 GHz ISM band. With a supply voltage of 0.5 V, the demodulator consumes 120 μW and demonstrates the demodulation of OOK and FSK at a data rate of 500 kbps. View Full-Text
