A 7.5 mW –43 dB LO leakage source‐driven wideband CMOS millimeter‐wave mixer

Abstract

Abstract 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 mm2 in area excluding signal pads.
