A 60 GHz CMOS OOK Receiver with 7.7 GHz Bandwidth for Wireless Proximity Communication

This paper presents a 60 GHz On-Off Keying (OOK) receiver with a 7.7 GHz baseband bandwidth for high-speed wireless communications. The receiver consists of a low noise amplifier (LNA), an envelope detector, and a limiting amplifier with DC offset cancellation. The envelope detector directly detects the OOK envelope signal from the LNA output signal, which helps minimize the power consumption. The channel bandwidth is widened via two techniques; a split inductor at the LNA load and a feedforward capacitor at the baseband limiting amplifier. Designed in a 65-nm CMOS process, the receiver consumes 17.5 mW from a 1 V supply, showing a conversion gain of 17.5 dB and a baseband bandwidth of 7.7 GHz, supporting up to 10 Gbps data rate.
