| Popis: | This paper deals with a wide band low noise amplifier (LNA) based on input output matching using stub. It describes the Low noise amplifier (LNA) network with different variety of matching networks at the input side and output side of RF receiver at 3.2 GHZ. It helps to differentiate the outcomes of ‘T’ type and ‘L’ type matching network. This circuit is designed and output graph is obtained with Advanced Design System (ADS) software. RLC feedback circuit is use to improve LNA network by a proper selection of a transistor type. Among all LNA matching circuits the T-L type matching gives better results in the stable region than L-L matching, L-T matching and T-T type matching. To obtain stability condition voltage gain and Noise Figure of T-L match is 14.141 db and 1.812 db which is better than L-L match as 10.391 db and 2.151 db, L-T match as 5.236 db and 2.46 db and T-T match is 6.468 db and 3.9db. |
