| Abstract: | A novel dual-band low noise amplifier applied in Wireless LAN is designed and fabricated in 0.18 μm CMOS process.In this dual-band LNA,by switching the input inductors and load inductors,the gain and impedance matching are achieved at the 2.4 GHz and the 5.2 GHz operation frequency bands,respectively.With a 1.8 V power supply,the LNA has a gain of 11.5 dB at 2.4 GHz and 10.2 dB at 5.2 GHz,and the noise figure of 3 dB at 2.4 GHz and 5.1 dB at 5.2 GHz,respectively.The total die area is 0.9 mm×0.65 mm. |
