Abstract :
A low power low noise ultra wideband LNA of 4 -13GHz is presented. It employs a series LC sections for input impedance matching, current reuse and noise cancellation technique to reduce the power consumption and noise. The designed LNA is implemented in standard 180nm CMOS technology using ADS tool. The designed LNA has a transfer gain of 21dB and noise figure of less than 3dB over the range of 4 -13 GHz band of frequencies with a power consumption of 18mW. It exhibits an input reflection co-efficient (S11) of less than -14dB within the entire band of frequencies and its IIP3 is -6dBm at 3GHz. Low power, low noise with high gain over the wide band of 4 – 13 GHz make it suitable for wide band RF front end.
