Abstract :
A 70.86 to 79.29 GHz low-power self-demodulator for on-off-keying (OOK) modulation is realized in TSMC 65-nm CMOS technology. By using a frequency-sweeping injection-locked oscillator (IJLO), the OOK modulated 70 GHz signal is demodulated by itself in a passive mixer and an 8.43 GHz bandwidth is achieved at 10.2 mW power consumption from a 1-V supply. The conversion gain is 10 dB and constant over the entire bandwidth. The core area of the chip is 0.072 mm2.
