Abstract :
A fully integrated low noise amplifier (LNA) suitable for ultra low voltage and ultra low power applications is proposed and demonstrated in 0.13 mum CMOS technology. In order to meet the requirement of ultra low voltage applications, a two-stage common-source configuration is employed. By using forward-body-biased metal oxide semiconductor field effect transistors, the proposed LNA can operate at 0.4 V supply voltage, successfully demonstrating the application potential of dynamic threshold voltage technology in the radio frequency region. The experimental results show that the proposed LNA has a 10.3 dB power gain and a 5.3 dB noise figure, while consuming only 1.03 mW dc power with an ultra low supply voltage of 0.4 V.
