1-Gb/s mixed-mode BPSK demodulator using a half-rate linear phase detector for 60-GHz wireless PAN applications

A mixed-mode high-speed binary phase-shift keying (BPSK) demodulator for IEEE802.15.3c mm-wave wireless personal area network (WPAN) application is realized with 0.18 mum CMOS process. The demodulator core consumes 23.4 mW from 1.8 V power supply while the chip area is 165 times 110 PMZ. The power-consumption is less than that of the conventional BPSK demodulators and the chip-size is smaller. The proposed circuit is verified by 1-meter 60-GHz wireless link tests with 1-Gb/s data.
