Low power high data rate GHz range receiver in 40nm CMOS technology

In this paper, a low power high data rate OOK receiver at GHz range is proposed. An injected locked ring oscillator based local oscillator is used for data demodulation. Implemented with a standard 40nm CMOS process, the receiver is able to recover an input signal with 1-4 GHz carrier frequency at the data rate of 50 Mbps while consuming less than 300 μW.
