© 2016 IEEE. This paper presents an ultra-low power super-regenerative receiver (SRR) suitable for OOK modulation. The receiver is fabricated in 40 nm CMOS technology and operates in the ISM band of 902-928 MHz. It exploits a SAR architecture to calibrate the internally generated quench signal. Employing an on-chip inductor and a single to differential architecture for the input amplifier has made the receiver fully integrable, eliminating the need for external components. A power consumption of 320 μW from a 0.65 V supply results in an excellent energy efficiency of 80 pJ/b at 4 Mb/s data rate, while the best sensitivity is -87 dBm at 1 Mb/s data rate.
