Abstract

A 3-5GHz CMOS low noise amplifier (LNA) for ultra wide band (UWB) receiver based on CMOS 0.18μm process is presented in this paper. To achieve low-power consumption and low noise, the proposed LNA employs current-reused technique via a PMOS cascade stage. The LNA provides a maximum forward gain (S₂₁) of 11dB while drawing 6mW from 1.2-V supply voltage. The LNA achieves 2.6-3.9dB noise figure (NF) in the frequency range of 3-5GHz. The measured P_in-1dB and IIP₃ of the proposed LNA are -16 and -3dBm, respectively. The size of the chip is 0.95mm × 0.77mm.
