摘要：
A low-noise amplifier (LNA) with tunable output matching network is designed for a frequency band 3.9 - 7.1 GM. The LNA gain can be tuned by varying the control voltage of varactor. The gain tuning range are 3 and 5.5 dB at 3.9 and 7.1 GHz, respectively. A maximum gain of 13.68 dB is obtained. The LNA consumes 22.8 mW with a supply of 1.5 V. The resistive shunt-feedback technique is used to design this broadband LNA. The LNA is fabricating in 0.18um standard CMOS process.
