An ultra low-power super-regenerative receiver for BFSK signals has been designed and fabricated in a standard 0.18 mum CMOS process. The use of BFSK allows the receiver to operate at higher data rates and also gives an approximate 3 dB SNR performance increase over the more traditional OOK modulation. At 1 Mb/s the receiver consumes 0.4 nJ/b making it the lowest energy integrated super-regenerative receiver to date.
