A 915MHz, 6Mb/s, 80pJ/b BFSK receiver with −76dBm sensitivity for high data rate wireless sensor networks

A mixer-less low energy BFSK receiver for wireless sensor networks is presented. Q-enhanced frequency-to-amplitude conversion and linear amplification at RF frequencies provide a large conversion gain and high data rates, leading to improved sensitivity and energy efficiency. Fabricated in a 0.13 μm CMOS process, the 915 MHz receiver, with integrated digital calibration, demonstrates a sensitivity of -90 dBm at 500 kb/s and an energy efficiency of 80 pJ/b at 6 Mb/s.
