Abstract

A 0.9-6 GHz broadband MOS based low noise amplifier with L type input matching network and π type output matching network is proposed for ultra wide band applications. The input L type matching network is used to fix the Q factor whereas the output π-type matching network provides an extra degree of freedom to adjust the bandwidth. The proposed circuit was designed and simulated by using AWR´s microwave office version 9.03; It is seen from the simulation results that the gain of ~ 22.7 dB for the frequency range of 0.9 to 6 GHz and noise figure (NF) of <;2.5 dB are obtained and found to be reasonably good in comparison to the reported works.
