A Fully Optimized Ultra Wideband Mixer in 65nm CMOS Technology

Abstract: This paper presents the design and analysis of Ultra Wideband (UWB) mixer in 65nm CMOS technology. To achieve the optimized performance, a new mixer topology is suggested. The performance parameters of the mixer viz.: conversion gain, Noise Figure, linearity and power consumption are addressed in this paper. The simulation results of the new mixer topology suggested in this paper achieves the reasonably good conversion gain (CG) of 7.27 – 10.92dB, a third order intercept point (IIP3) of +2.01 to +6.7dBm and Noise Figure (NF) of 10.4 to 12.4dB between entire band of 3.1-10.6GHz while consuming only 3.6mW of power from 0.8V supply.
