چکیده مقاله
A low power ultra wideband UWB low noise amplifier LNA is proposed exploiting a current reused and forward body bias techniques operating in the frequency range of 3 1 10 6 GHz The first stage of the UWB LNA employs a resistive shunt feedback topology in conjunction with a parallel LC load to achieve wideband input matching and low noise figure simultaneously By incorporating the current reused configuration and forward body bias technique in the second stage, the proposed UWB LNA can operate at reduced supply voltage and power consumption while maintaining high gain, low noise The proposed LNA is designed for UWB applications using 180 nm TSMC CMOS process The implemented ultra wideband LNA presents a minimum power gain of 17 65 dB, a high reverse isolation of −31 5 dB and a good input / output return losses are better than −10 1 dB in the frequency range of 3 1–10 6 GHz An excellent noise figure NF of 2 35–2 58 dB was obtained in the required band with a power dissipation of 5 92 mW under a supply voltage of 1 V An input referred third order intercept point IIP3 is −18 dBm at 6 GHz
