文摘

A novel low-IF double balanced CMOS Gilbert mixer with high linearity and conversion gain is presented in this paper. An innovative easy-implemented cross-coupled full differential multiple gated transistor topology is proposed to improve the linearity while maintaining the high conversion gain. In addition, a topology, which artfully combines the current-bleeding technology and the noise-cancelling technology, is introduced to reduce the noise figure. The prototype of the proposed circuit was fabricated in SMIC 0.18?μm CMOS process with a chip area of 0.32?×?0.24?mm2. The measurement results have exhibited an IIP3 of 10.2 dBm and a conversion gain of 17.8?dB with a power dissipation of 3.6?mW from 1.8?V supply. Compared to recently published studies, the proposed work has achieved a higher FoM.
