High gain bulk-driven down conversion mixer with improved noise figure for UWB system

This paper presents a high gain, high linearity and improved noise figure double balanced mixer at 3.432 GHz RF frequency using 180 ηm CMOS technology. To improve the performance of the circuit, LC matched bulk driven technique with biasing transistors in sub threshold region is utilized in this paper. The simulation results shows the maximum gain of 8.748 dB at 3.432 GHz RF frequency, double sideband noise figure of 4.586 dB and (IIP3)of 14.65 dBm.
