A 3.1-10.6 GHZ Ultra-Wideband CMOS Low Noise Amplifier in 0.18 μm CMOS Technology

A new ultra-wideband 3.1-10.6 GHz low noise amplifier(LNA), designed in chartered 0.18μm technology, is presented in this paper.By using series inductive peaking in the feedback loop is used to improve the basndwidth of the LNA. Based on the noise-canceling technique,voltage gain is increased. Measurements show that the S11 and S22 are less than -10 dB, and the maximum amplifier gain S21 gives 12.9dB, and the minimum noise figure is 2.6dB, and the power consumption is 13.6 mW from 1.8V supply voltage.
