Recently, the high speed device to device(D2D) wireless communication technology has been studied for short distant mobile data transfer application. This paper presents 60 GHz OOK(On-Off Keying) non-coherent receiver which is a strong candidate for high speed D2D communication technology. The OOK receiver architecture is used because of its simple structure and low power characteristic. The receiver consists of three-stage low noise amplifier (LNA), fully differential envelop detector, and limiting amplifier(LA). The measured receiver shows 54 dB peak gain at -55 dBm input power level. The sensitivity of the receiver is measured -50 dBm under 3 Gbps data rate. The proposed receiver is fabricated with 65 nm CMOS process and its measured power consumption is only 21.5 mW. As a result, the proposed receiver achieves energy efficiency of 7.12 pJ/bit.
