Abstract :
A bi-directional active resistor structure with quasifloating gate MOS transistors and non-linearity compensation is used in a resistive negative feedback wide-band LNA implementation enabling a continuously tunable gain from 0dB to 24dB. The LNA has been realized in 65nm CMOS with a minimum noise figure of 2.5dB and IIP3 of -8dBm at highest gain. The LNA bandwidth is from 100MHz to 2GHz, with a power consumption of 12mW and an active area of 0.0375mm2.
