Design of an Ultra Low Power Low Noise Amplifier for 5-GHz band

This paper is presented an ultra low power Low Noise Amplifier (LNA) for 5-GHz frequency band. The operating voltage of this Low Noise Amplifier is 0.63 V. By using these techniques forward-body-bias and Current-reuse DC power dissipation is reduced. Capacitive Coupling is used for gain boosting. Simulation result shows the Noise Figure (NF) of 4.1 dB and 21.4 dB of gain at 5-GHz with 0.63 V operating voltage & power dissipation is 0.48 mW. This LNA is implemented using 180 nm TSMC library.
