Abstract
This paper presents an E-band I/Q demodulator in 90-nm CMOS process. The demodulator attains -3-dB conversion gain with only 26.6-mW power consumption and 4-dBm LO power by adopting push-push based sub-harmonic mixers with a tunable 45 �X power divider. With the amplitude and phase calibration mechanism, the demodulator achieves outstanding IRR higher than 40 dBc from 76 to 88 GHz, and demonstrates gigabit data rate transmission of 8.2% EVM 16-QAM modulation. This demodulator exists competitive performance whatever in conversion gain, LO power, modulation quality or power consumption compared with other published MMW demodulators.
