Abstract :
A low-power transceiver for wireless sensor networks at sub-GHz frequency bands is presented, which integrates an RF frontend as well as a digital baseband and a MAC layer into a single 3.0 mm2 chip. The transceiver covers 169/300/400/900 MHz bands and supports FSK/GFSK modulation with a data rate from 1.2 to 200 kbps. A prototype is fabricated in 65 nm CMOS, achieving only 8.2 mA in the RX and 23 mA in the TX with +10 dBm output power at 915 MHz from a 3.3 V supply.
