This paper presents the design and experimental results of low power CMOS single-chip for 868 MHz and 915 MHz bands wireless sensor network applications based on IEEE 802.15.4 standard; especially RF transceiver part. Single-chip radio consists of RF transceiver section and digital baseband section. Implemented in a 0.18 μm CMOS technology the receiver shows sensitivity of -100dBm and -93 dBm in BPSK and OQPSK modulation schemes, respectively, and dynamic range of 80 dB. The transmitter path shows a maximum of +10 dBm output power with EVM of less than 6.8% RMS and 12% RMS in BPSK and OQPSK modulation schemes, respectively. The RF transceiver consumes 16 mA in receive mode and 24.5 mA in transmit mode under supply voltage of 1.8 V in which 5 mA of frequency synthesizer is included. The implemented single-chip occupies 16 mm2 silicon area in which 10 mm2 is used for the RF transceiver section. © 2013 IEEE.
