Design of UWB low noise amplifier using noise-canceling and current-reused techniques
چکیده انگلیسی
In this paper, an ultra-wideband (UWB) low-noise amplifier (LNA) with low noise-figure (NF) and high power gain (S21) using 0.18-um CMOS technology is presented, which operates from 3 GHz up to 12 GHz. In the proposed amplifier, a combination of noise-canceling and current-reused technique is used to reduce noise and power consumption, while the gain and the linearity will be improved. The dominant noise source is canceled by the noise-canceling technique. In addition, good input impedance matching is achieved with using both the inductive source degeneration and resistive feedback techniques. The proposed LNA achieves high and flat S21 of 19.24-20.24 dB and S11 less than −10 dB for frequencies 3-12 GHz. Additionally, flat NF of 1.72-1.99 dB is achieved for the frequency range of 3-12 GHz. Furthermore, the IIP3 is −5.5 dBm, power consumptions at 1.8-V supply voltage is 23.23 mW and the core layout size is 857.06 µm×770.72 µm.
