摘要：

A high linearity up-conversion mixer operating at 700 similar to 900MHz with 1V supply using 0.18 mu m CMOS technology is proposed in this paper. This up-conversion mixer is composed with two double-balanced mixers and is based on the Gilbert mixer. The quadrature differential signals are put to the mixer, and the output of the mixer will be added in the form of current, that achieves the quadrature modulation. The up-conversion mixer takes advantage of current-reuse bleeding, which can improve the conversion gain and reduce the noise figure. In addition, the positive feedback structure is used in this up-conversion mixer so that the conversion gain will be improved further. From the simulation result, the mixer demonstrates 3.39dB conversion gain, 0.097dBm input 1dB compression, 9.57dBm IIP3 and 22.28dB noise figure with 1.36mW power dissipation from a 1V supply.
