Abstract: In this paper, Noise analysis of a novel MODFET LNA was done that is designed using Micro strip based design methodology. A novel design has been proposed for MODFET LNA Load and stability has been obtained. A comparative analysis has been done for different values of drain voltages. Noise analysis has also been done and the design is carried out at a centre frequency of 2.4 GHz and the noise bandwidth considered is 6GHz. In this paper the work is carried out using ADS simulation software. Scattering parameter S11 and S22 are obtained. Noise figure and gain of Cascaded LNA is also obtained. Variation of noise figure and gain with respect to frequency has been obtained. From the results the effect of drain voltage on the design performance is explored. Layout of the proposed design has been obtained. Results obtained are in greater coherence with the theoretical observations.
