A CMOS single-chip transceiver design for 700/800/900MHz wireless sensor network applications

This paper presents a low-power CMOS single-chip transceiver for sub-GHz wireless sensor network applications, which complies IEEE 802.15.4-2012 standard. It embodies RF transceiver section based on direct-conversion transmitter and low-IF receiver architecture. To validate its operation, the prototype is fabricated in 0.18um GF standard CMOS process. It shows +5dBm TX output power and -85dBm RX sensitivity. Furthermore, RX dynamic range reaches up to 90dB. The transceiver consumes 26mA and 18mA for TX and RX operations under 1.8V supply voltage, respectively. It occupies 10mm² active area for the RF transceiver section.
