Abstract. An ultra wide band (UWB) receiver front-end operates at the UWB frequency range, starting from 9 GHz-10.6 GHz is proposed in this paper. The proposed system consists of an off-chip microstrip antenna and CMOS differential low noise amplifier with a differential noise canceling (DNC) technique. The proposed antenna is trapezoidal dipole shaped with balun and printed on a low-cost FR4 substrate with dimensions 10x10x0.8 mm3. The balun circuit integrated with the ground antenna to improve the antenna impedance matching. Full-wave EM solver HFSS (High Frequency Structure Simulator) is used for modeling the proposed antenna. The CMOS LNA is designed using UMC 0.13µm CMOS process, and exhibits a flat gain of 19dB, maximum noise figure of 2.9 dB, 1dB compression point -16dBm, 3rd order intercept point (IIP3) -10dBm, and DC power consumption of 2.8 mW at 1.2 V power supply. Applying the noise canceling stage, the NF is reduced by 50% to be 2.75 dB while the power consumption is increased to be 2.9mW.

Keywords: ultra-wideband (UWB), low noise amplifier (LNA), differential noise canceling, low power, low noise figure.
