A low area fully reconfigurable multi-band LNA array based on active feedback amplifiers with mixed resistive and switched inductor loads is presented. The 90nm baseline digital CMOS implementation covers the entire frequency range of interest for SDR from 0.1 to 6GHz with a dynamic gain range from 0dB to 22dB. A noise figure as low as 2.7dB and an input-referred linearity IIP3 of -4dBm at 16dB gain is achieved. An IIP3 of +9dBm is reached in low gain mode to allow for high signal and interferer power at the antenna input. The LNA draws between 10 and 26mA from a 1.2V supply. The active area of the array is only 0.045mm2 .
