Abstract:
A 94 GHz down-conversion mixer for image radar sensors using standard 90 nm CMOS technology is reported. The down-conversion mixer comprises a double-balanced Gilbert cell with peaking inductors between RF transconductance stage and LO switching transistors for Conversion Gain (CG) enhancement and Noise Figure (NF) suppression, a Marchand balun for converting the single RF input signals to differential signals, another Marchand balun for converting the single LO input signals to differential signals, and an IF amplifier. The mixer consumes 22.5 mW and achieves excellent RF-port input reflection coefficient of -7.1~ -35.9 dB for frequencies of 82.6~96 GHz, and LO-port input reflection coefficient of -10~ -35.9 dB for frequencies of 88.2~110 GHz. In addition, the mixer achieves CG of -3.4~ -6.4 dB for frequencies of 85~97 GHz (the corresponding 3-dB CG bandwidth is 12 GHz) and LO-RF isolation of 41~47.2 dB for frequencies of 90~100 GHz, one of the best CG and LO-RF isolation results ever reported for a down-conversion mixer with operation frequency around 94 GHz. Furthermore, the mixer achieves an excellent input third-order intercept point (IIP3) of -3 dBm at 94 GHz. These results demonstrate the proposed down-conversion mixer architecture is promising for 94 GHz image radar sensors.
