Abstract

A ultra-wideband (UWB) low noise amplifier (LNA) was designed and fabricated in 0.18μm CMOS technology. The successful integration of current-reused and forward body biasing (FBB) techniques in a cascade amplifier can enable an aggressive scaling of the supply voltages, Vdd and Vg1 to 1.0V and 0.53V The low voltage feature from FBB leads to more than 50% saving of power dissipation to 5.2mW. The measured power gain (S21) can reach 10.55∼12.6dB and noise figure (NF50) is 3.2∼3.95 dB through the UWB (3∼10.5GHz). This UWB LNA with small chip area (0.69mm2) provides a solution of low voltages, low power, and low cost.
