Design and Comparison of Low Power High Gain and Low Noise Figure LNA for ISM Applications

Objectives: This paper represents the design and simulation of LNA (Low Noise Amplifier) for ISM (Industrial, Scientific and Medical) applications operating in the 2.4-2.5 GHz band. Methods/Statistical Analysis: In this paper, a very accurate topology named inductive source degeneration topology has been used to provide low NF (Noise Figure), high S21 (forward gain) and very low Power Consumption (PC). The simulation was made through using Advance Design System (ADS) software. Findings: The proposed work prominence on reduction in Noise Figure with increase in power gain at low power consumption as compared to published previous results at 1.2 V power supply. Improvements: This is done in three steps (three different schematic designs) i.e. start with very basic LNA design to proposed LNA design and presents the comparison of all three designed circuit simulations.
