Abstract :
In this paper, a fully integrated concurrent multiband low noise amplifier (LNA) for WLAN and WiMAX is presented. The target frequency bands included 802.11 b/g@2.4 GHz, 802.11a@5.2 GHz for WLAN and 802.16d@3.5 GHz for WiMAX. The output matching network is constructed of shunt-peaking with inter-stage matching. Itpsilas easy to achieve matching and reduced chip size to only 0.75 mm2. The power gain of LNA is 11.79 dB at 2.4 GHz, 11.70 dB at 3.5 GHz and 10.06 dB at 5.2 GHz. And NF are 3.89 dB at 2.4 GHz, 4.03 dB at 3.5 GHz and 3.73 dB at 5.2 GHz;input and output return loss are below -10 dB for all desired frequency bands. The design is simulated by TSMC 0.18 um RF CMOS process. With 1.4 V voltage supply, the power dissipation is only 13.5 mW.
