Abstract :
A multi-band 900 MHz/1.8 GHz/5.2 GHz low noise amplifier (LNA) which can operate at mobile band of 900 MHz and 1.8 G and WLAN band of 5.2 GHz frequency is proposed. Input matching, noise matching and narrow gain are achieved at three frequency bands by adopting a switched output load and a resistive shunt-feedback circuit. The proposed LNA is designed in TSMC 0.18 um CMOS technology with a supply voltage of 1.8 V. The LNA has gains of 14 dB, 13 dB and 16 dB and noise figures of 2.3 dB, 2.9 dB and 2.7 dB at 900 MHz, 1.8 GHz and 5.2 GHz frequency bands, respectively, while dissipating power of 7.5 mW at all frequency bands.
