Design of a Novel Low-Power and Highly Linear UWB Low Noise Amplifier

This paper presents a low power,highly linear and high gain LNA,the circuit of which adopts common-gate（CG）topology to achieve input matching,utilizes the forward body biasing and current reuse techniques to reduce power consumption.Meanwhile,in order to achieve a high linearity,the proposed LNA utilizes post-distortion technique.The simulation results show that the proposed LNA has good performances under the condition of low power consumption.
