A 7.5 mW-43 dB LO leakage source-driven wideband CMOS millimeter-wave mixer
This paper presents a millimeter-wave (mm-wave) V-band mixer. The source-driven transformer-coupled up-converter topology can alleviate the local oscillator (LO) leakage problem. The proposed V-band up-converter has been implemented on 65 nm CMOS technology. The experimental results show that the LO leakage level can be reduced to -43.1 dB. The up-converter occupies 0.11 mm(2) in area excluding signal pads.
