This paper presents a design flow and an optimization methodology of an ultra wideband up-conversion mixer designed on CMOS 0.18 μm technology. The circuit, designed to be integrated in IR-UWB transmission architecture for a medical application, is based on a doubly balanced Gilbert topology. Models for conversion gain, noise figure and linearity were developed for the Gilbert cell to estimate optimum transistors sizing and biasing and thus to obtain good performances. Based on these models and trying to enhance the performances of the mixer’s characteristics, a new method using a current injection technique was presented to design the mixer. The circuit has shown good results since it exhibits about 11.5 dB conversion gain, a moderate noise figure of about 8.8 dB, a better linearity with an IIP3 of about 2.3 dBm and a low power DC consumption in the range of 5.6 mW.
