Abstract :
A 4.5-GHz low-noise amplifier (LNA) utilizing a current-reused technique and a simple LC matching network is proposed. The implemented LNA presents a maximum gain of 35.22-dB by using inductive peaking technique, and a good input matching of 50Ω in the required band. An excellent noise figure (NF) of 2.255-dB was obtained in the frequency range of 4.5-GHz with a power dissipation of 5.04mW under a 1.2-V power supply, and achieve input return loss (S11) of -21.96-dB, output return loss (S22) of -17.84-dB, and reverse interest (S12) of -66.38dB. This work is implemented based on SMIC 0.13μm CMOS technology.
