A 60-GHz transceiver system with low-power CMOS OOK modulator and demodulator

Abstract

A 60GHz transceiver system with low-power CMOS OOK modulator and demodulator is presented in this paper. The 60 GHz modulator is designed in a 90-nm CMOS process by current reuse and consumes 14.4-mW dc power at the ON-state. A data rate of up to 2 Gb/s has been measured. The 60GHz OOK demodulator is designed in a 130nm CMOS process. The demodulator consumes 14.7 mW, and recovers up to 5 Gb/s with the gain boosting detector and baseband amplifier. The fabricated 60 GHz modulator and demodulator are successfully integrated in an LTCC SiP transmitter module and receiver module with 1 by 2 patch antenna, respectively. Using these LTCC SiP modules, 648 Mb/s wireless video transmission was successfully demonstrated at 20-cm wireless distance.
