In this paper a low-noise-amplifier is presented which is operating for multi-standard wireless application which
includes GSM (DCS1800) 3G (UMTS) band applications. By employing forward-body-biasing technique along with currentreuse technique our proposed design is working at very low bias voltage while maintaining high gain. The LNA shows an
excellent standard of gain with low dissipation of DC power and minimal noise figure. Low noise figure and high gain is
achieved by employing positive feedback in transformer coupled source follower configuration. 0.18 µm CMOS process is used
to design proposed LNA. The simulated result shows that re-configurability of LNA is from 1.86 GHz to 2.1 GHz. It achieves a
power-gain of 14.46 dB to 4.43 dB at 1.86 GHz and from 24.68 dB to 7.49 dB at 2.10 GHz, minimum noise figure of 2.14 dB, DC
power dissipation of 1.43 mW and maximum IIP3 of -6.27 dBm.
