Abstract :
This paper presents a 3.1-10.6GHz low power and low noise amplifier(LNA) band on the cascode configuration. The circuit design consists of RC-feedback and forward body bias technique. The measurement results show the proposed UWB CS LNA can achieve a maximum power gain (S21) of 10.8dB with the 3dB bandwidth from 3.1GHz to 10.6GHz. The input reflection coefficient S11 and output reflection coefficient S22 are lower than -8.1dB and -9.5dB, respectively. A minimum noise figure of 5.5 dB, and an input third-order intercept point IIP3 of -6.4dBm. The power dissipation is 6.4mW at 1.1V supply voltage. This LNA occupies an area of 1.1*0.88mm2.
