Improved 0.18μm CMOS down-conversion mixer for UWB systems

This paper presents the CMOS Down-Conversion Mixer for UWB systems., The circuit is simulated under 0.18μm TSMC CMOS technology. Common mode feedback is used in the circuit and buffer stage is used to provide th impedance matching. The Passive RLC matcing is used at the input ports. The simulation result shows the conversion gain 15.484dB with noise figure of 15.894dB and IIP3 value of 10.009dBm. The Power consumption the MOSFETs used in the circuit is 40mW.
