Gbps 60GHz CMOS OOK Modulator and Demodulator

New 60GHz OOK modulator and demodulator are presented in this paper. A proposed 60GHz OOK modulator is designed in a 90nm CMOS process by current reuse and dual modulation technique and has 28.5dB high on/off isolation, and 10dB gain at 60GHz with 14.4mW at on-state of an OOK digital signal. It can process OOK digital signals up to 2Gbps. Measured OP1dB is 1.5dBm. A proposed 60GHz OOK demodulator is designed in a 130nm CMOS process with gain boosting circuits and baseband amplifiers and restores a 5Gbps OOK digital signal with 14.7mW DC power dissipation.
