Abstract :
This paper proposes a reconfigurable low noise amplifier (LNA). The proposed LNA equips variable bias circuit and can be reconfigured by bias voltage of transistors. It contributes to power reduction, compensation of intermodulation, and output signal to noise ratio (SNR out). The proposed LNA achieves 73 % of power reduction by controlling bias voltage, and dynamic compensation of DeltaIM3 and SNR out is realized
