This paper presents the design of a fully-integrated RF low noise amplifier with active inductor linearizer. The proposed circuit achieves 16 dBc of third order intermodulation IM3 distortion cancellation at 1.9 GHz with 8 dB third-order intercept point IP3 improvement. The proposed circuit utilize an active inductor linearizer to improve linearity of the circuit and offering tunability. The simulation results show an overall proposed circuit peak gain is 14.5 dB and the minimum noise Figure is 0.75 dB at 1.9 GHz frequency with power consumption of 7.4 mA. © 2021 IEEE.
