A 2-V, LOW DISTORTION, 1-GHZ CMOS UP-CONVERSION MIXER

A 1 GHz, very linear, CMOS up-conversion mixer is presented. The circu it is able to operate at a 2-V power supply. The topology has a true s ingle-ended output stage which avoids the use of any balun. The total power consumption in both the mixers and the output stage is only 22 m W at 2 V. A profound analysis of the origins of distortion in the mixe r has been performed. This study has resulted in the optimization of t he linearity of the realized up-conversion mixer. The low power consum ption, the low supply voltage, the high frequency performance, and the relatively large amplitude and low distortion single-ended off-chip o utput signal make the presented topology very suitable for wireless ap plications.
