A Low Voltage Wideband CMOS Mixer with High Linearity

Hung-Che Wei

Abstract—A low voltage wideband CMOS down-conversion mixer is described. The gm-boosted and the current-bleeding techniques are employed to improve the linearity of the proposed mixer. The mixer implemented by tsmc 0.18 μm CMOS process achieves maximum input third-order intercept point (IIP3) of 2.6 dBm, power conversion gains of 6.9 dB, and single side-band noise figure (SSB NF) 20.8 dB. The mixer operates over the entire 1.4–3.6 GHz LTE-advanced bands and consumes 6.5 mA of current from a 1.2 V power supply.

Index Terms—4G, CMOS, LTE-advanced, linearity, low voltage, mixer
