Abstract :
A 3.5GHz CMOS low noise amplifier (LNA) for WiMax receiver based on CMOS 0.18 μm process is presented in this paper. To achieve low-power consumption and low noise, the proposed LNA employs complementary and current-reused techniques. The LNA provides a gain (S21) of 11dB while drawing 6.5mW from 0.75-V supply voltage. The LNA achieves 4.6dB noise figure (NF) in the frequency of 3.5GHz. The measured P1-1dB and IIP3 of the proposed LNA are -18 and -9dBm, respectively. The size of the chip is 0.95 mm × 0.85 mm.
